A first locking portion that has a cut at a location, and that locks at one end of the cut with a locking portion provided on the outer periphery of another component tube member of the lens barrel to restrict rotation around the optical axis. What is claimed is: 1. A lens barrel comprising: an exterior barrel having a fixing portion provided at the other end of the cut end for fixing the exterior barrel to the barrel member. (2) The inner diameter of the outer barrel is made by means such as molding so that it is larger than the outer diameter of the lens barrel,
The lens barrel according to claim 1, wherein the inner circumferential length of the exterior barrel is equal to the outer circumferential length of the lens barrel. (3) The lens barrel according to claim (1) of the utility model registration, characterized in that the other end of the cut has a second locking part that locks with the first locking part. (4) A third locking part is provided on one end side of the cut, and the third locking part is connected to the first locking part, and the third locking part locks with the second locking part and locks the exterior. The lens barrel according to claim 2, wherein the barrels are connected in a closed loop. (5) Markings and scales are provided on the outer surface or outer peripheral end surface of the outer cylinder.
Utility model registration claim No. (1) characterized in that a mark such as a symbol is displayed, and a long groove is provided in the first locking part through which a screw for fixing the one end to the constituent cylinder member passes. The lens barrel described in items (3) to (3) above.
