Abstract: The lens holding frame is accommodated in the outer tube and is movable with respect to the outer tube in an optical axis direction (OAD) parallel to an optical axis of a lens optical system. The intermediate holding frame is a flexible frame body that constitutes the lens holding frame, is formed of a flexible material, and has a tubular shape. The intermediate holding frame is integrally provided with beam structures as abutments. The beam structures abut onto an inner circumferential surface of the outer tube in a state of being elastically deformed such that a restoring force is generated and prevent vibration caused by a gap between an outer circumferential surface of the lens holding frame and an inner circumferential surface of the outer tube.
