Abstract
A lens barrel of the present invention includes: a fixing frame having a plurality of cam grooves that are formed an inner circumferential surface of the fixing frame and also having a protrusion provided between any adjacent two of the cam grooves among a plurality of the cam grooves; and a drive frame having cam followers that are provided to an outer circumferential surface of drive frame, are engaged with the cam grooves, and are movable along the cam grooves. With this configuration, when an external force is applied to the drive frame, an end portion of the drive frame comes into contact with the protrusion to prevent the cam followers from coming out of the cam grooves.
