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). Further, the stop ring (6) is attracted to the flange (8) of the stationary frame (7) by the magnetic attractive force acting between the multipolar magnet (12) and the body portion (24A) of the sheet metal part (13), so that backlash is removed.
