Summary: | PROBLEM TO BE SOLVED: To provide a lens barrel to which a straight advance guide member can be attached without requiring an attachment member. SOLUTION: A straight advance guide member 25 has an annular portion 25a. In the straight advance guide member 25, a cut 25a1 which can elastically deform the annular portion on a surface orthogonal to an optical axis is formed in the annular portion 25a. A circumferential groove 22e is formed on the inner circumferential surface of a rotating frame 22 and the annular portion 25a is fitted into the circumferential groove 22e by using elastic deformation, so as to allow the relative rotation of the rotating frame 22.
