A seafloor crust A is dug into by an excavation tube 31, whereby a circular annular groove 50 is formed and a circular-cylindrical geological sample provisional part 51 is formed radially inward from the annular groove 50. Next, a harvesting tube 41 is inserted into the annular groove 50, the harvesting tube 41 having a cylindrical tube body 41a and a protrusion 41b provided to the inner periphery of the lower end part of the cylindrical tube body 41a. A moment is then imparted, via the site on the harvesting tube 41 that projects from the crust A, so as to cause the harvesting tube 41 to tilt. This pushes the protrusion 41b against the geological sample provisional part 51 and breaks the geological sample provisional part 51, whereby a geological sample 55 is obtained. Next, the harvesting tube 41 is raised while the geological sample 55 is held within the harvesting tube 41.

An axial end part 11 of a cylindrical pipe 10 is fixed by a conical recess 31 of a main-shaft-side chuck 30 and a conical projection 41 of a mandrel 40, a spinning roll 50 is then pressed against the cylindrical pipe 10, which is supported by a columnar part 42 of the mandrel 40, and the thickness of the cylindrical pipe 10 is reduced. The clamping mechanism in the present invention is therefore simpler than in conventional spin forming and fewer steps are involved; therefore, processing time can be reduced. Because the spinning roll 50 is pressed against the cylindrical pipe 10 supported by the columnar part 42 of the mandrel 40 and the thickness of the cylindrical pipe 10 is reduced, the shape of the cylindrical pipe 10 after thickness reduction is simpler than in the prior art, and the inside diameter thereof is substantially constant except for the axial end part 11. The mandrel 40 can therefore easily be applied to forming various types of wheel rims.

An inner multi-piece rim (20) has an outer bead sheet band (23), an outer side ring (25), an inner bead sheet band (26), and an inner side ring (28). Therefore, when a tire (T20) is removed from a rim base (21) of the inner multi-piece rim (20), the tire (T20) can be removed with an assembly containing the outer bead sheet band (23), the outer side ring (25), the inner bead sheet band (26), and the inner side ring (28). Therefore, the assembly structure of the tire (T20) removed from the rim base (21) of the inner multi-piece rim (20) can be made identical to an assembly structure of a tire (T10) removed from a rim base (11) of an outer multi-piece rim (10). Consequently, the labor and time for replacing tires can be reduced in comparison with conventional practice.

Because the groove side inclined surface (31) is inclined axially outward with respect to the wheel and radially outward with respect to the wheel, compared to a case where the groove side inclined surface (31) is cylindrical, the groove (30) is less deep, and the minimum thickness of the exterior bead seating section (24) is greater at the wheel axial direction position at which the groove (30) is formed. Thus, the strength of the rim (20) can easily be maintained even if the groove (30) is formed in the exterior bead seating section (24).

The disc has a hub installation section (10a), spokes (10b) radially extending from the hub installation section toward the outer peripheral edge of the disc, and a ring-shaped disc flange (10c) connected to the spokes via curved surface connection sections (R) formed by folding the outer peripheral ends of the spokes into the direction of the axis of the wheel. The disc flange extends in the direction of the axis of the wheel. A portion surrounded by adjacent spokes, the hub installation section, and the disc flange is defined as a decoration hole (20). Among the portions where the inner peripheral surface of the rim and the outer peripheral surface of the disc flange are fitted together, portions facing head ends (12) of the spokes are welded.
Provided is a method for manufacturing a spoked wheel disc, which is improved in productivity and production yield and reduced in a poor weld to its rim. The manufacturing method comprises a preforming step of forming a plurality of raised portions (110) for the basis of reinforcing portions (11) of spoke portions in a substantially circular panel blank (100), concentrically on the outer circumference side than bolt holes (10e), an opening step of opening a plurality of ornamental prototype holes (200) in the raised portions, thereby to form spoke prototype portions (100b) between the adjoining ornamental prototype holes, a disc flange forming step of forming a disc flange (10c) by bending the outer circumference portion of the panel blank having the opened ornamental prototype holes, perpendicularly into parallel to the wheel axis direction, thereby to constitute the upper end edge of the disc flange with the outer edges of the ornamental prototype holes formed, and a spoke portion forming step of forming the spoke portions (10b) by forming the reinforcing portions at the spoke prototype portions.

Intended is to provide a jig, which does not require the worker to hold a lock ring against the radially shrinking elastic force and to support the weight of the lock ring. The lock ring mounting/demounting jig is constituted of a set of two jigs (41 and 42), which are jointed by a single screw bolt (8) and can be individually mounted on the two end portions (4a and 4b) of a lock ring (4). The paired jigs (41 and 42) are constituted to include body portions (or blocks (41B and 42B)) and clamp portions (41C and 42C) such that the clearance between the set jigs (41, 42, 410, 420, 411 and 421) can expand and contract.
A wheel for vehicle includes a wheel body, a decorated member, and a visible space. The wheel body has a rim, a hub, and a plurality of spokes connecting the hub and the rim. The decorated member is made from resin, is disposed on a surface of at least one of the spokes, and is retained to the wheel body. The visible space is disposed between the decorated member and the one of the spokes at least, exhibits a height in an axial direction of the wheel body, and is visible from an axial outer side of the wheel body.
A crawler belt 20 includes first regions and second regions alternately arranged in a circumferential direction thereof. The first region has at least one first tread lug 25 and the second region has at least one second tread lug 26. The first tread lug 25 has high flexural rigidity and is not easily bent and the second tread lug 26 has low flexural rigidity and is easily bent. The first tread lug 25 catches on an upper end of a high step or bump S with the second tread lug 26 in a bent condition, thus allowing the crawler unit to move over the step or bump.
A multi-piece rim which does not need much labor for supporting, and does not increase the number of components to be managed and the number of needed tasks. A lock ring (40) to be fitted in the groove (11a) of a gutter band (11) is divided into a plurality of portions (41, 42), and they are coupled at one end (41a, 42a) of each through a flexible coupling member (43). Alternatively, a lock ring (140) is formed into a substantially C-shape obtained by cutting a part of a circular ring, and is constituted of a first portion (141) where the length of a chord at the cut portion is substantially equal to the diametral dimension of a hub, and a second portion (142) having a shape corresponding to that at the cut portion of a circular ring in the first portion.
[PROBLEMS] A small-sized crawler device capable of stably traveling over a step and stairs. [MEANS FOR SOLVING PROBLEMS] The crawler device includes a device body (1) having main crawler tracks (20) on its left and right and an auxiliary crawler track provided, as an auxiliary member, at one end of the device body. To make the crawler device go up a step or stairs with the auxiliary crawler track (30) positioned behind the main crawler tracks (20), a controller (65) is set to a preparatory condition where the auxiliary crawler track (30) is set free relative to the main crawler tracks (20) or is held at a position above, by a predetermined angle, a line extended from the main crawler tracks (20). When the tilt angle of the device body (1) detected by a tilt sensor (60) reaches an angle equal to or greater than a threshold angle after the main crawler tracks (20) start to go up the step, the auxiliary crawler track (30) is controlled to rotate it downward. This reduces the tilt angle of the device body (1) to prevent it from toppling backward.
An SnCu based lead-free solder alloy for manual soldering that enables production of a solder of stable composition with resistance to soldering iron tip thinning nearly equivalent to that of Sn37Pb (eutectic alloy). The SnCu based lead-free solder alloy is one comprising 0.1 to 1.5 wt.% Cu and 0.05 to 0.5 wt.% Ag, and further comprising 0.01 to less than 0.05 wt.% Co and 0.01 to 0.05 wt.% Fe, with the balance consisting of Sn. Accordingly, there is obtained a solder simultaneously having excellent iron thinning resistance and composition stability. Not only enhancement of iron thinning inhibition but also copper thinning inhibition can be attained by still further comprising 0.001 to 0.05 wt.% transition metal or misch metal being a mixture thereof.
