Abstract
A lens barrel includes a first lens, a second lens, a first frame body, a second frame body, and a retracting lens frame. The retracting lens frame is configured to move so that a position of the second optical axis of the second lens changes from a position on the first optical axis of the first lens to a position that is outside the first optical axis, during the transition period between the imaging enabled state and the housed state. A contact portion is formed on the inner peripheral part of the first frame body. A protrusion of the retracting lens frame is configured to engage with and guided by the contact portion during movement of the retracting lens frame. The thickness of a region constituting the side wall of the contact portion is increased over the thickness of the other region toward the inside of the cylindrical part.
