Abstract
An apparatus for positioning an automobile in an extremely limited area such as that in a parking lot. The apparatus has a pair of carriages for carrying left and right wheels of the vehicle and movable in the breadthwise direction of the vehicle, a pair of guide bars having inclined portions for progressively engaging the inner or outer surfaces of the vehicle wheels as the vehicle moves onto the apparatus, a spring for urging the guide bars to standard positions where the guide bars are in symmetry with each other with respect to the longitudinal axis of the limited area, and a racks-and-pinion mechanism which is arranged such that, when one of the guide bars is displaced by the vehicle wheel in the breadthwise direction of the vehicle, the other guide bar also is moved in such a manner that both guide bars are always maintained in symmetry with each other with respect to the axis of the limited area.
