PURPOSE: To enable the driving of a vehicle to a proper position by providing guide strip bodies in parallel on a turntable, a detecting panel for controlling the rotation of the turntable via the indexing of each neutral position between front and rear wheels and further a vehicle stop position detecting sensor.

CONSTITUTION: When a front wheel at one side of a vehicle steps down a part of the running board 61 of a detecting panel 60 and the other front wheel comes on a part of the running board 61, the panel 60 detects a distance between the front wheels and calculates a neutral position P. Then, when the panel 60 detects the shift of the neutral position P, the turntable 50 rotates until the point Q thereof agrees to the neutral position P. Then, both of the aforesaid front wheels upon passage through the detecting panel 60 and reaching the turntable 30, come on guide strip bodies 40 and 41 on the turntable 30. Thereafter, rear wheels come on the strip bodies 40 and 41 through a similar process. Furthermore, when the strip bodies 40 and 41 turn to forcibly haul the vehicle forward and a stop sensor 50 detects the vehicle, the strip bodies 40 and 41 are stopped.
