PURPOSE: To prevent a vehicle from breaking through a door of a vehicle entrance and intruding indoors so that no vehicle may drop into the opening of a lift.

CONSTITUTION: In a parking space, whose type is provided with a housing chamber on a lower floor than the entrance of vehicles and transfers vehicles by means of a lift down to the level of the housing chamber, a pair of posts on both sides are installed in a spacing wider than an opening of a vehicle entrance between a door 1 and a lift opening 7. A car stopper fence 12 is fixedly installed to a vertically slidable fence lift lever 14 so that the fence 12 may be hooked at a hook 13 fixed with the door 1. Then, interlocking with the door 1, the fence 12 is arranged to slide vertically by the power of an open close drive device of the door 1.
