The apparatus includes an axle rotatably mounted on the car floor, a radially extending operating arm for contact with anedge of the car door panel, at least one radially extending stop arm and a return spring for retracing the stop arm when the car door panel is closed. As the cardoor panel is opened, the stop arm is rotated adjacent a stop on the wall of theelevator shaft in which the car travels. If the stop is a recess formed in the shaft wall, a free end of the stop arm cooperates with the recess to prevent drift. If the stop is a floor door threshold, two stop arms are provided to prevent drift superposed above and below the threshold.
