PURPOSE:To ensure the accurate positioning of a truck, by forming a positioning projection to the truck and a positioning member having a positioning groove at the side of the floor surface respectively and forming a tapered side to both the projection and the groove to fit them together when the truck is moved horizontally. CONSTITUTION:A positioning projection 18 is provided to a goods carrying and unmanned guide truck 1, and a positioning member having a pair of V-shaped positioning grooves 15a is set to a mobile device provided on the floor surface. A tapered side is formed to both the projection 18 and the groove 15a. When the truck 1 is moved horizontally from its traveling path by a free wheel 3, an interlocking member 12 of the truck 1 is fitted to the upper part of the member 15. In this case, if there is some shift between the center of the projection 18 and that of the groove 15a, this error is automatically corrected when the projection 18 is put into the groove 15a since they have a tapered side respectively. As a result, the truck 1 can always be positioned accurately to the mobile device. |
