Disclosed is a lens device including a click mechanism of a ring member that is rotated with respect to a lens barrel body, slides in the optical axis direction, has high slidability during a click operation and high durability, and can prevent one-sided abrasion due to the inclination of the ring member. A click mechanism of a first focus ring includes: elastic members for clicking provided at three equally divided positions on the circumference of a front fixed ring of a lens barrel body; and a contact portion that is formed in a central portion of the inner circumferential surface of the first focus ring and comes into contact with a convex portion of the elastic member for clicking. The elastic member for clicking is made of polyacetal with high slidability. Therefore, it is possible to reduce the abrasion of the elastic member for clicking during a click operation.
