PURPOSE:To stabilize the slide motion and the like of a slider and improve the reliability of rotation control by providing the slider on one of a rotor and a board and a rotation signal generation pattern on the other, and energizing the rotor toward the board via a cushion material. CONSTITUTION:When a motor provided in a casing proper 1 is applied with voltage via a connector 5, an output shaft 7 turns via a reduction gear mechanism 3 and a lever 6 is thereby driven. In this case, with the turn of the reduction gear mechanism 3, a rotor 10 constituting a rotation control part 4 is made to turn. Also, with the rotation of the rotor 10, a slider 14 is made to slide on a rotation signal generation pattern, thereby outputting a change in the resistance value of a terminal 17 or a circuit. And a fine gap is formed between the rotor 10 and an output shaft 7 coupled therewith, and the mechanical strain of the output shaft 7 is thereby absorbed. Furthermore, the rotor 10 is energized toward a board 12 via a wave washer 13, thereby absorbing a vibration and the like. |
