PROBLEM TO BE SOLVED: To eliminate the need of an O ring cover when a gap between a shaft part of a mover for mirror surface angle detection and a hole of a sensor case is sealed by the O ring.SOLUTION: O rings 104, into which shaft parts of slide blocks 90, 92 are inserted, are sandwiched between a sensor case 95 and an actuator housing 12. The sensor case 95 and the actuator housing 12 are fastened to each other by screws 86. The O rings 104 are crimped and held between the sensor case 95 and the actuator housing 12 by a screw fastening force. |
