PROBLEM TO BE SOLVED: To provide a vibration-proof actuator that can determine whether or not an image blur-proof lens is in an engagement state without providing a dedicated sensor.SOLUTION: The present invention relates to a vibration-proof actuator (10), and the vibration-proof actuator includes: a stationary part (12); a movable part (14) that has an image blur-proof lens (16) attached; a movable part support member (18); a driving coil (20); a driving magnet (22) that is attached so as to face the driving coil; a magnetic sensor (24) that detects magnetism of the driving magnet; an engagement mechanism (42) for engaging the movable part upon non-execution of image blur-proof control; a vibration-proof control part (36a) that drives the movable part on the basis of the detection signal of the magnetic sensor and performs image blur-proof control; and an engagement control part (36b) that determines whether or not the movable part is engaged based on a detection pattern of the magnetism upon the non-execution of the image blur-proof control and when the movable part is not engaged, controls the engagement mechanism (42) to engage the movable part. |
