摘要： A lens barrel includes an optical lens having an optical axis, an operation ring substantially cylindrical and operable about the optical axis to move the optical lens along the optical axis thereof, and a slidable contact member slidably in contact with the inner circumferential surface of the operation ring, the slidable contact member providing a specific load against the inner circumferential surface thereof. The operational torque of the operation force is changed when the slidable contact member moves in the optical axis direction by changing its contact area with the inner circumferential surface of the operation ring.
