Mesh with gears 16, 16 formed on the outer peripheral surfaces of the front and rear traveling rollers 9, 9. Reference numeral 17 is a guide member formed on the lower surface of the base body 8, which is loosely inserted into a groove formed below the rail 2 so as to regulate the lateral swing of the traveling device 1.

A strip-shaped trolley wire is laid over the entire length on the inner surface of the upper plate of the rail 2. The trolley wire has a predetermined number of power supply / transmission bars 6 running in parallel and the power supply / transmission bar 6 It is composed of an insulating plate 7 provided above. A plurality of trolley wires 3 each having a predetermined length are connected in parallel to each other in the longitudinal direction, and an insulating material 19 is interposed in each of the connecting portions 18. It should be noted that electric power, signals, and the like are supplied or transmitted to the unit-length power supply / transmission bar 6 via the power supply members 20, respectively.

A mounting member 22 is erected on a mounting plate 21 formed at the end of the base body 8 of the traveling device 1.
