Abstract
A lens barrel in which a lens can be moved in a direction parallel to an optical axis includes: a first frame having a cam follower and a cam follower base that holds the cam follower; and a second frame that has a cam groove engageable with the cam follower. The first frame and the second frame are moved relatively to each other along the optical axis. The cam follower base has a first end connected to the main body of the first frame via at least one thin portion, and a second end not connected to the main body. The thin portion is formed such that a thickness of the thin portion in a radial direction of the lens barrel is smaller than that of the cam follower base.
