发明名称 LENS BARREL
摘要 PROBLEM TO BE SOLVED: To arrange a focusing lock part to a desired position at the time of AF(autofocusing) without causing the cost to rise. SOLUTION: This lens barrel is equipped with a manual focusing ring 4 provided to be manually rotated around an optical axis and rotated to perform focusing operation; a focusing lock part 16 provided on the ring 4, rotated together with the ring 4 by the rotation of the ring 4, and holding a focusing state; and a focusing mode switching part 5 for switching the focusing mode to a manual focusing mode or an autofocusing mode. When the focusing mode is switched to the autofocusing mode side, the ring 4 is not rotated by autofocusing operation but can be rotated manually.
