PROBLEM TO BE SOLVED: To provide a lens barrel including a vibration-proofing optical element moved to a separation position getting out of a vibration-proof driving position in a housed state, and in the lens barrel, to prevent harmful light from entering a supporting ring that movably holds the vibration-proofing optical element with simple and compact structure.SOLUTION: The lens barrel includes: a first moving member and a second moving member which hold the vibration-proofing optical element, and are supported to be movable in directions different from each other in a plane orthogonal to an optical axis of an optical system within the supporting ring; a vibration-proof driving means which suppresses image blur on an imaging surface by driving the first and second moving members in accordance with the magnitude and direction of shake applied to the optical system; an inserting/removing drive mechanism which moves the second moving member that supports the vibration-proofing optical element directly between the vibration-proof driving position, where positional control by the vibration-proof driving means is possible, and a separation position getting out of a position control range by the vibration-proof driving means; and a radial-direction through-part which is formed in the supporting ring and allows the vibration-proofing optical element to advance when the second moving member is at the separation position; wherein a light shielding wall part, which is located at the rear of the radial-direction through-part in the supporting ring and intercepts a light beam entering the supporting ring from the radial-direction through-hole, is formed in the first moving member. |
