Is embedded. The overhead lines 11, 11 project from the side surfaces of the linear overhead line main body 1A and the curved overhead line main body 1B, and are formed in arc shapes that are convex outward. The material of the linear overhead wire main body 1A and the curved overhead wire main body 1B is rubber or synthetic resin having an insulating property. It is preferable that the curvilinear overhead contact line main body 1B be prepared with an arbitrary curvature and an arbitrary curve according to the required shape of the traveling path. Further, it is preferable to prepare a plurality of lengths of the entire length of the linear overhead wire main body 1A. Wires 12 connected to the overhead wires 11 are wired inside the linear overhead wire main body 1A and the curved overhead wire main body 1B.

In addition, it is easy to change the traveling path. As described above, the upper concave portion 13 is formed at one end of the linear overhead wire main body 1A and the curved overhead wire main body 1B, and the lower concave portion 14 is formed at the other end. Since only the overhead wire main body 1A or the curved overhead wire main body 1B can be used, the types of components can be reduced, and the manufacturing cost can be reduced.

  As shown in FIGS. 1 and 2, the current collector 3 includes a slider holding plate 31 formed by bending a non-conductive plate material into a trapezoid, sliders 32 and 32, a hollow cylindrical support cylinder 33, a compression coil spring 34, 35, and a guide roller 36.

The sliders 32, 32 are fixed to the inner lower ends of both side plates of the slider holding plate 31, and contact and slide with the overhead wires 11, 11 of the linear overhead wire main body 1A or the curved overhead wire main body 1B, and the self-propelled vehicle 2 is fed. In the embodiment of the present invention, since direct current is used, one overhead wire 11 is on the plus side, and the other overhead wire 11 is on the minus side. When three-phase alternating current is used, three overhead wires 11 and three sliders 32 may be arranged. The sliders 32, 32 are formed of carbon, a copper-based sintered alloy, or the like. A guide groove 17 having a rectangular cross section is formed over the entire length in the longitudinal direction on the upper surfaces of the linear overhead wire main body 1A and the curved overhead wire main body 1B. A guide roller 36 is rotatably mounted on the lower surface of the upper surface of the slider holding plate 31 so as to protrude downward in the vertical direction. The guide roller 36 fits into the guide groove 17 and rolls to guide the current collector 3 along the linear overhead wire main body 1A and the curved overhead wire main body 1B.

  A support cylinder 33 is attached to the upper surface of the upper surface of the slider holding plate 31 so as to protrude vertically upward.
