Title: ACTUATOR
Abstract:
In order to reduce the planar area of an actuator (1), a first magnetic drive circuit (6) and a third magnetic drive circuit (8) that vibrate a movable body (3) in an X direction with respect to a support (2) are provided respectively on both sides, in a Z direction, of a second magnetic drive circuit (7) that vibrates the movable body (3) in a Y direction with respect to the support (2). The movable ranges, in the X direction and the Y direction, of the movable body (3) with respect to the support (2) are restricted by a stopper mechanism constituted between a first magnet (621) and a first coil holder (65) holding a first coil (61), a stopper mechanism constituted between a second magnet (721) and a second coil holder (75) holding a second coil (71), and a stopper mechanism constituted between a third magnet (821) and a third coil holder (85) holding a third coil (81).
