筒。[Scope of Claim for Utility Model Registration] In a lens barrel in which a focusing operation or a focal length change operation is performed by rotating an operating ring that is rotatable in the circumferential direction with respect to a fixed barrel, the fixed barrel has an optical axis direction. A locking position setting ring whose movement is regulated and whose movement in the radial direction is restricted is mounted on the operating ring so as to be rotatable in the circumferential direction with respect to the operating ring, and the locking position setting ring is mounted circumferentially with respect to the operating ring. It can be fixed at any position in the direction by a fixed operation member,
Further, a locking member that applies a biasing force in the optical axis direction is provided on either the fixed lens barrel or the locking position setting ring, and a locking member that applies a biasing force in the optical axis direction is provided on either the fixed lens barrel or the locking position setting ring. A lens barrel characterized in that a locking hole portion into which a locking portion of the locking member fits is provided.
