Abstract
A lens barrel includes an outer barrel including a first cam follower, an internal movable member including a second cam follower, a cam ring, a first cam groove formed on a surface of the cam ring and engaged with the first cam follower, and a second cam groove formed on the surface of the cam ring and is open at a front end of the cam ring. When the outer barrel is positioned in front of a predetermined position, the second cam groove determines a position of the internal movable member in the outer barrel via a limit portion while the second cam groove is not engaged with the second cam follower, and when the outer barrel moves rearward beyond the predetermined position, the second cam groove engages with the second cam follower and moves the internal movable member rearward.
