  • Publication number: 20210215999
    Abstract: There is provided a lens barrel from which stable operation feeling of an operation ring is obtained regardless of part accuracy. A stop ring (6) is provided with a ring-shaped multipolar magnet (12) that is magnetized to have multiple poles at regular angular intervals in a circumferential direction. A stationary frame (7) is provided with a sheet metal part (13). The sheet metal part (13) includes a body portion (24A) and a protrusion portion (13B). The body portion (24A) is disposed on a flange (8) of the stationary frame (7), and the protrusion portion (13B) is disposed on the outer periphery of the stationary frame (7). The stop ring (6) is click-stopped at regular angular intervals by a magnetic attractive force acting between the multipolar magnet (12) and the protrusion portion (13B) of the sheet metal part (13).
