特徴とするレンズ鏡筒。[Scope of Claim for Utility Model Registration] An externally fixed lens barrel, which fits into the inner periphery of the externally fixed lens barrel, and transmits the driving force from the camera body to the focusing lens in order to drive the focusing lens. A sliding member fixed to the driving force transmitting lens barrel;
a circumferential groove formed on the circumference of the externally fixed lens barrel to maintain the position of the driving force transmitting lens barrel; an internally fixed lens barrel that fits into the inner peripheral side of the driving force transmitting lens barrel; a lens drive member that slides on the fixed lens barrel to move the lens; and a position adjustment member that is fixedly installed on the internal fixed lens barrel and that works in conjunction with the lens drive member to finely adjust the lens drive member in the optical axis direction. The position adjusting member is arranged on the internal fixed lens barrel so as to be in a positional relationship opposite to the circumferential groove, and the position adjusting member is adjustable via the circumferential groove. lens barrel.
