a fixed member;
a first movable member that is movable with respect to the fixed member in an optical axis direction;
a holding member that holds an optical element and is movable with respect to the first movable member in the optical axis direction;
a guide member that is held by the first movable member and guides the holding member in the optical axis direction;
a second movable member that is movable with respect to the fixed member in the optical axis direction independently of the first movable member; and
a drive unit configured to drive the holding member in the optical axis direction,
wherein the second movable member holds the drive unit so as to restrict displacement of the drive unit with respect to the second movable member in the optical axis direction, and
wherein the drive unit is disposed entirely on an outer peripheral side of the first movable member.
