The invention relates to a drive apparatus having a spindle (6) which is driven by a drive for actuating an actuating element. Supporting means are provided which are connected fixedly to the spindle (6) and can be moved against a spring bearing. If forces which exceed a predefined maximum value act on the spindle (6), the spring bearing is compressed and the supporting means are pressed against a stationary stop. As a result, the drive is decoupled from these forces.
