Patent ID: 8905656

Claim:
A lens barrel comprising: a lens tube configured to hold a lens; a barrier driving member configured to move between an opened state and a closed state by switching of the lens tube between a shooting-ready state and a retracted state; a pair of first barrier blades, each of which includes a blade portion, configured to open and close in conjunction with the barrier driving member; a pair of second barrier blades, each of which includes a blade portion and a coupling portion, the coupling portion positioned outside the lens as viewed from an object side and located closer to the first barrier blade than the blade portion, the pair of second barrier blades being configured to be moved by contact between the coupling portion and the first barrier blade, and wherein the second barrier blade further includes a closing coupling portion that is a downward bent portion for transmitting a motion from an end surface of the first barrier blade to the second barrier blade, the closing coupling portion being folded back by an angle equal to or greater than 90° and less than 180°, and when the second barrier blade is at a closed position, the closing coupling portion prevents a front end of the first barrier blade from swaying in an optical axis direction.
