PURPOSE:To improve the economical property of a guide device for a self- traveling dolly without providing any fixed guide device to the path but by setting a path guide device to the dolly itself. CONSTITUTION:A fixed departure-arrival place guide device 4 is provided to a departure-arrival place 3 of a self-traveling dolly 5, and no fixed guide device is provided to a path 1. Then a path guide device consisting of a distance detector 11 and comparators 13 and 14 is set to the dolly 5. For the dolly 5 loading goods and started at a point A, a steering motor is controlled so as to obtain a fixed distance between the dolly 5 and a wall 2 at the left side. Thus the dolly 5 travels on the path 1 toward the place 3. |
