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 memberhave the regions exhibiting the different rigidities, and when an external force is exerted on the elongated structurefor 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. Therefore, the elongated structurefor 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 structurefor the movable section become smaller, but also it is possible to cut down a cost necessary for such a protective guide structure.

Elongated structure for movable section

A power supply device comprises a capacitance (Ca) consisting of an overhead power line () and an electrode () extending in the longitudinal direction of the overhead power line () via an insulator (), an inductance (La) connected in parallel with the capacitance (Ca), and an output portion () led out from both ends of a parallel circuit including the capacitance (Ca) and the inductance (La). The parallel circuit is operated as a parallel resonant circuit and power is supplied from the output portion (), thereby obtaining a compact and simple structure and improving power supply efficiency to a load as compared with a conventional power supply device.
