To prevent the extrusion of grease due to the movement of a pin at the time of moving the pin in a control groove by forming a space between each end of the control groove and the pin even in the case where the pin reaches the end of the control groove.
A device 1 for driving a damper 2 is formed of a driving lever 3 to be turned by a motor actuator 5 and a driven lever 4 to be driven by this driving lever 3. In this case, when the driving lever 3 is operated by the motor actuator 5, a pin 7 is moved to a left end, and the driven lever 4 is turned clockwise around a driving shaft 8 as a fulcrum. When the pin 7 abuts on a stopper 10b, the driving lever 3 is stopped. Furthermore, when the pin 7 is moved to a right end for return, the driving lever 3 abuts on a stopper 10a and stops. With this structure, a space is formed in a left and a right ends 9a, 9b of a control groove 9, and the grease is left in these spaces so as to prevent the extrusion of the grease.
