This sliding bearing comprises a pair of semicircular half bearings formed into a cylindrical shape by bringing both circumferential ends thereof into contact with each other. The axial width of the half bearings is narrower in both circumferential ends and the circumferential center, and wider in the quarter parts located therebetween.

Contaminants such as wear particles that have infiltrated between the counterpart member and the sliding surface fail into the discharge grooves and then are discharged outside of the sliding surface.

The outer periphery of the outer part of a substrate is a chamfer, and the outer part of the substrate is covered by a resin film layer. The thickness of the resin film layer at the chamfer is thicker than the locations radially further inwards from said chamfer. The surface of the resin film layer on the outer peripheral edge of the outer part is coplanar with the surface of the resin film layer further inwards. These locations act as the sliding surface (the surface of the swash plate) that slides on a shoe, and compared with conventional techniques, because the resin film layer in the outer peripheral edge is thick, attrition of the portion being pressed against the shoe is suppressed. For that reason, the outer peripheral edge of the substrate and the vicinity thereof are prevented from being exposed, and seizure of the swash plate can be prevented.

A sintering condition is set such that Bi moves outside particles of said Cu—Bi containing Cu-based powder and forms a Bi grain-boundary phase free of In, and In diffuses from said Cu—In containing Cu-based powder to said Cu—Bi containing Cu-based powder.
A molding device for manufacturing a molded product having an inner space bent in a circular arc shape includes: a set of molds joinable to and separable from each other, the set of molds being capable of forming a cavity having a shape corresponding to an outer shape of the molded product in a joined state at the time of molding; a core having an outer shape corresponding to an inner shape of the molded product for use in a state where the core is arranged in the inside of the cavity formed by the set of molds at the time of molding; and an ejector plate having a core through hole through which the core passes for ejecting the molded product formed around the core along the circular arc shape in a separated state where the set of molds is separated from each other.
A piston cooling jet includes a housing, a nozzle, a valve, a pressure chamber, a pressure adjusting passage, and a filter. The nozzle is provided to project outward from the housing, and capable of spraying oil toward a piston. The valve is capable of moving reciprocally inside the housing, and configured to receive a load due to a hydraulic pressure in an engine-side oil passage applied from a front side of the valve. The valve includes a valve-side oil passage that communicates with the engine-side oil passage. The pressure chamber communicates with the valve-side oil passage. The pressure adjusting passage is disposed between the pressure chamber and a space outside the housing. The filter is disposed in the valve, and configured to remove foreign matter that cannot pass through the pressure adjusting passage from oil passing through the valve-side oil passage.

In a bearing apparatus provided herein a hard steel shaft is an opposite shaft of an Al—Sn—Si based alloy plain bearing. Its wear resistance is enhanced. The bearing apparatus comprises a steel shaft having hardness of Hv 500 or more at least on a surface thereof, and a plain bearing. The plain bearing is formed of an aluminum alloy containing 2 to 10 mass % of Si, 8 to 18 mass % Sn, and the balance being Al and unavoidable impurities, wherein the volume of Sn phase is 50% or more of the volume of the Si particles(the average particle diameter of Si of the aluminum alloy is 4 to 10 μm). The aluminum alloy has a hardness of Hv 45 or more.
a of the piston 4. A columnar portion 13 is formed between the spherical surface portion 11 and the end surface portion 12 in the shoe 5, and in a boundary area between the columnar portion 13 and the spherical surface portion 11, there is formed a spherical-surface-portion side flange 14 which protrudes radially outward and constitutes the spherical surface portion.
