Claim Text:
1. A lens barrel comprising: a motor; an input transmission ring rotated by the motor, the input transmission ring being rotatable around an optical axis; and a lens drive cylinder connected to the input transmission ring so that rotating force is transmitted from the input transmission ring, the lens drive cylinder moving a lens in an optical axis direction and being rotatable; an automatic input ring rotated by the motor, the automatic input ring being rotatable around the optical axis; and at least three interlocking members that interlock the input transmission ring with the automatic input ring, wherein the lens drive cylinder is placed on one side of the motor in the optical axis direction, the input transmission ring is placed on the same side of the motor as the lens drive cylinder, each of the interlocking members includes a roller shaft held by the input transmission ring, and a rotating roller rotatably supported by the roller shaft, the rotating roller rotates the automatic input ring as the automatic input ring rotates, and the input transmission ring rotates around the optical axis as the rotating roller rotates.
