筒。[Claims for Utility Model Registration] (1) A lens barrel support member; A hollow outer barrel; One or more lens barrel constituent members housed within the hollow portion of the outer barrel; A fixing member for fixing an outer barrel; and a rotation restricting means for restricting rotation of the lens barrel constituent member relative to the support member around an optical axis; A lens barrel, wherein at least one of the lens barrel constituent members is held between the support member and the outer barrel, thereby being restricted from moving in the optical axis direction. (2) At least two of the lens barrel constituent members are provided, both of the lens barrel constituent members are arranged in conjunction with each other in the optical axis direction, and the rotation limiting means moves one of the lens barrel constituent members to the support member. Claim for utility model registration characterized by comprising a fixing member for fixing and a rotation limiting member for preventing relative rotation of one lens barrel constituent member and the other lens barrel constituent member around the optical axis. Lens barrel according to scope 1. (3) The outer tube has a rear end fixed to the support member and a front end opposite to the rear end, and a ring is provided between the inner surface of the front end and the lens barrel component. The lens barrel according to claim 1, characterized in that a mold gasket is clamped. (4) A mounting seat is attached to the rear end of the outer cylinder,
2. The lens barrel according to claim 1, wherein a planar gasket is clamped between the mounting seat and the support member by the fixing member.
