Claims

[Claims for Utility Model Registration] 1. A first annular member, and a first annular member that is arranged around the first annular member and that is rotated about the optical axis or displaced in the optical axis direction in response to an operating force. a second annular member; an elastic member disposed in a gap between the second annular member and the first annular member and capable of being elastically deformed in the radial direction; A lens barrel characterized in that the lens barrel includes a tightening member that is attached to the elastic member, contacts the elastic member to elastically deform the elastic member, and presses the elastic member onto the first annular member. 2. The elastic member is composed of a leaf spring having an elongated shape in the circumferential direction, and an elastic body fixed to the inner peripheral surface of both ends of the leaf spring, and the tightening member is attached to the outer periphery of the intermediate part of the leaf spring. The lens barrel according to claim 1 of the utility model registration, which is in contact with a surface. 3. The lens barrel according to claim 2, wherein the intermediate portion of the plate spring does not come into contact with the second annular member even when the tightening member is tightened to its full stroke. 4. The second annular member is a fixed ring, and the first annular member is attached to the second annular member so as to move forward and backward in the optical axis direction as it rotates. The lens barrel according to scope 1.
