OPTICAL CORRECTION UNIT, LENS BARREL AND IMAGING APPARATUS

PROBLEM TO BE SOLVED: To provide an optical correction unit capable of setting a reference position of a correction lens with high accuracy by eliminating a rotational error of a movable member at a mechanical end without making the unit larger, and to provide a lens barrel and an imaging apparatus. SOLUTION: The optical correction unit includes: first to third driving means respectively moving the movable member 115 in first to third directions orthogonal to an optical axis of the correction lens 111; first to third supporting means respectively provided in areas opposed to the first and third driving means across the optical axis and supporting the movable member 115 to a base member 121; and first to third position detection means respectively detecting positions of the movable member 115 in the first to the third directions. The optical correction unit is provided with first to third position regulation means respectively regulating movement of the movable member 115 in the first to the third directions around the first to the third supporting means.
