Air flap driving device

Air flap driving device (10) comprises a damping unit for damping torque (24) exerted onto the air flap. Preferred Features: The device has a drive shaft (18) which lies on a pivoting axle (14). The damping unit has a coupling element (20) and a damping element (22). The coupling element is coupled with the drive shaft and with the damping element. The coupling element and the damping element are coupled so that small movements of the drive shaft are transferred into larger movements which are damped by the damping element. The damping element is a silicone oil damping element.
