Adjustment device for a motor vehicle headlamp

The adjustment device has an optically relevant component, which is moved by an actuator. A drive element (8) of the actuator moves a rolling element (9), which is rotatably mounted in a bearing piece (18). The movement of the rolling element in the movement direction of the drive element causes a stubby movement of an adjusting element (3). The drive element is moved linearly by the actuator, and the rolling element has two peripheral surfaces (13), which are connected with each other by a shaft piece.
