ABSTRACT:
Disclosed is an actuator device for an optical device. The actuator device includes a core arranged in an optical device inside of which an optical path passes through, a coil wound around the core, and a rotational magnet formed into an approximately cylindrical shape, at least one end of which includes a bearing portion in an axial direction, and which rotates according to a direction of a magnet field output from the core by electrifying the coil. The actuator device further includes a drive pin rotated in association with the rotational magnet, a base member securely supporting the core and rotatably supporting the rotating magnet, and an optical member moving in and out of the optical path based on rotation of the rotational magnet.
