Abstract

A motor vehicle contains a device (1) for controlling the shifting movement of a closure element by means of a shifting drive (5) fixed on the closure element. A transmission element (11) is mounted on a support console (7), which is connected fixedly to the closure element, which transmission element is movable relative to the support console (7), is mounted movably by a bearing region (13, 15) on a body region and is coupled by a coupling region (18), which faces away from the bearing region (13, 15), to the shifting drive (5) in order to transmit mechanical forces.
