ABSTRACT:
A lens barrel is configured so as to rotatably support lens barriers by a barrier drive member that rotates around an optical axis and the lens barriers rotate and revolve on an axis when the lens barriers are opened and closed. The lens barrel includes wall units provided on an inner circumference portion facing to a space where the lens barriers of the lens barrel member operates, and convexes provided on surfaces of the lens barriers adjacent to the inner circumference portion of the lens barrel member. When the lens barriers are held at a barrier opening position and the barrier drive member is moved to a driving member closing position, the wall units are brought into contact with the convexes and the lens barriers are forcibly closed.
