Abstract
A lens barrel is provided which includes a stationary frame and a second holding frame. One end of a second main rod is attached to the second holding frame with a sleeve between. One end of the second sub rod is fixed to the second holding frame, and the other ends of the second main rod and second sub rod are attached to the stationary frame so that the second main rod and second sub rod can freely slide. Consequently, the second holding frame is borne while being permitted to freely advance or withdraw relative to the stationary frame without rotating by the main rod and second sub rod. The main rod is fixed to neither the stationary frame nor lens holding frame but can slide by itself. Therefore, even when the lens barrel is collapsed, the main rod will not jut backward beyond the stationary frame.
