ACTUATOR AND LENS BARREL EQUIPPED WITH ACTUATOR

摘要

Provided is an actuator with improved thrust and a lower weight for a magnetic field generating member constituted by a magnet and a yoke, in comparison to a conventional actuator. The actuator according to the present disclosure comprises: a magnetic field generating member having a multi-pole magnetized magnet and a yoke disposed on one of the multi-pole magnetized surfaces; and a coil member provided at a position opposing the other multi-pole magnetized surface. The yoke is constituted by a member that has a width narrower than the multi-pole magnetized surfaces.
