PROBLEM TO BE SOLVED: To improve the adaptability of the switching angle of a switching gear for the target stroke of a movable member that can travel in the on/off device of a drive device for driving the movable member that can travel between reference positions. SOLUTION: In the on/off device of an electric motor for driving a movable member 25 that has a switch device for stopping a drive electric motor 21, at least, at one predetermined position of the movable member 25 and can travel between reference positions, a switching gear 17 that is rotated and moved at an angle that is smaller than 360 degrees via an eccentricity transfer mechanism 23 when the member moves between reference positions for operating the switch device and the eccentricity transfer mechanism 23 is constituted in two stages. |
