In an elongated structure for a movable section, a plurality of operational linear elements such as conductive wires are arranged in parallel in a belt-like sheath member, and an outer region of the sheath member, which is defined by a bend of the sheath member, has a larger rigidity than that of an inner region of the sheath member, which is defined by the bend of the sheath member. When the sheath member 2 have the regions exhibiting the different rigidities, and when an external force is exerted on the elongated structure 1 for the movable section, it is apt to bend toward the side of the sheath member having the small rigidity, and the bent portion is maintained at a given curvature which is determined by the entire rigidity of the sheath member 2. Therefore, the elongated structure 1 for the movable section cannot easily meander while the movable end thereof is moved. Also, while the position of the bent portion is shifted, it is possible to stably carry out the movement of the movable end and the shift of the bent portion. In addition, a protective guide structure is not needed, and not only can an installing space for the elongated structure 1 for the movable section become smaller, but also it is possible to cut down a cost necessary for such a protective guide structure.

Disclosed is an electromagnetic field sensor, by which discriminating operation can be simplified, and a cable can be discriminated rapidly and correctly. The clamp-type sensor (30) is provided with: a substantially annular electrode (31), which is composed of a nonmagnetic material having conductivity, and which surrounds a part of a cable in the circumferential direction in a state where the cable is clamped; a magnetic core (33), which is composed of a magnetic material, and is disposed on the outer side of a ring (31a) of the electrode (31) with an insulator (32) therebetween; a winding wire (34), which is wound around the magnetic core (33); and an output section (35), which is led out by means of a lead wire (35a) from the electrode (31), and led out from both the ends of the winding wire (34) by means of a lead wire (35b). An inductive current generated in the winding wire (34) due to electromagnetic induction is outputted from the output section (35), and a voltage generated in the electrode (31) due to electrostatic induction is outputted from the output section (35).

A streak material for movable sections that has multiple actuation streak materials such as conductive wires provided in a prescribed parallel arrangement, within a flat-band like sheath member, and which has the portion of the sheath member that will become the outer-side, when the sheath member is bent, made to have a higher rigidity than the inner side portion. Since, on the one hand, this streak material (1) for movable sections will be bent, when an external force is applied, to the side having lower rigidity between the two sides of a sheath member (2) having different rigidities, and on the other hand, the bent portion will be maintained at a prescribed curvature due to the rigidity of the sheath member (2) as a whole, the streak material (1) is not liable to meander when an end portion of the same is moved or the location of the bent portion is changed, and moving an end portion or changing the location of the bent portion can be conducted in a stable state. In addition, since there will be no need for a protection guide, the installation space can be made narrower, and the cost necessary for protection guides can be reduced.
Provided is a display device for a storage battery, which has a simple constitution but can display the state of electrolyte precisely and which can be manufactured at a low cost. The incident light from the root end portion (11) of a transparent member is reflected on or transmitted through a slope portion (13) in accordance with the state of the electrolyte, so that it is directed, only if transmitted, toward a projected portion (15) at the tip end. At least a portion of the transmitted light is reflected on the chromatic face of the projected portion (15) so that it reaches the root end portion (11). Therefore, the display mode at the root end portion (11) of the case, in which the electrolyte is so short that it fails to contact the slope portion (13), is made an achromatic display accompanying the reflection of the light. In case the electrolyte is so sufficient that it contacts the slope portion (13), on the other hand, the root end portion (11) can display the color of the chromatic face of the projected portion (15). Thus, the difference from the display mode of the root end portion (11) between the individual cases of short and sufficient electrolytes can be enlarged to ensure the recognition of the state of the electrolyte shortage by the user.
