ABSTRACT:
A lens barrel has a first group frame provided with a rotating frame having a cam groove and made of a synthetic resin and a cam follower made of a synthetic resin integrated with the circumferential face for relative movement with the rotating frame and engaged with the cam groove, in which a shaft member made of metal is inserted into the center portion of the cam follower. If the lens barrel is dropped and the first group frame undergoes a relatively large impact force, the impact force acts between the cam groove and the cam follower, but since the shaft member is inserted into the cam follower as mentioned above, breakage of a root portion of the cam follower is prevented, and since the cam groove and the cam follower are both resin, plastic deformation on the cam groove side is also prevented.
