PURPOSE:To lay a guide path easily and inexpensively and improve reliability by laying a coil in a branching part of the guide path in the branch direction and providing a switch, which opens and closes the loop of the coil, on this coil. CONSTITUTION:A metallic sensor 2 which is movable in proportion to the steering angle of a wheel 3 is attached to a body 1 of an unattended wagon, and a metallic band 5 arranged on a path floor 4 as the guide path is detected by this sensor 2 to guide the unattended wagon. In case that this guide path is branched, guide coils 10a and 10b are provided in branching parts in branch directions. Switches 11a and 11b are provided on coils 10a and 10b, and the direction in which the unattended wagon is branched and guided is selected by switching of these switches 11a and 11b. |
