摘要：
Balls are clamped between a first gear driven by an auto-focusing motor and a second gear driven by a manual focusing ring. The balls are arranged to revolve about a given axis. A projection having an elasticity and provided to the second gear itself is brought into contact with a fixing member provided at a predetermined position, so that a clamping force for clamping the balls is generated by the projection.
