Claim 0:
1. A lens barrel comprising:
a stationary frame including a first frame body and a second frame body;
a first movable frame that is configured to hold a first optical member and is supported by the first frame body so as to be movable in a direction of an optical axis of the first optical member;
a first drive unit including a first magnet provided to the first movable frame and a first coil provided to the first frame body, the first drive unit configured to move the first movable frame in the direction of the optical axis of the first optical member;
a second movable frame that is configured to hold a second optical member and is supported by the second frame body so as to be movable in a direction of an optical axis of the second optical member or in a direction orthogonal to the optical axis of the second optical member; and
a second drive unit including a second coil provided to the second movable frame, and a second magnet provided to the second frame body and a yoke which is made of magnetic body and fixed to the second magnet, the second drive unit configured to move the second movable frame in the direction of the optical axis of the second optical member or in the direction orthogonal to the optical axis of the second optical member,
wherein, in a case where the first movable frame is moved to a moving end close to the second drive unit and application of current to the first coil is stopped, the first movable frame is fixed at the moving end by a magnetic force between the first magnet provided to the first movable frame and the yoke provided to the second frame body,
the second movable frame is a barrel body that is supported by the stationary frame so as to be movable in the direction of the optical axis of the second optical member and has a cavity on a side thereof facing the first movable frame, and
the first movable frame enters the cavity of the second movable frame in a case where the first movable frame is moved to the moving end close to the second drive unit.
