摘要： An addendum of a gear portion and a tip end of a first cam follower are located on similar-diameter cylindrical planes centering at a center axis of a cam ring. A gear housing recess is provided in an inner peripheral surface of a fixed ring. A bottom surface of a first-cam-ring-movement cam groove engaging with the first cam follower, and a bottom surface of the recess are located on similar-diameter cylindrical planes centering at a center axis of the fixed ring. A release portion is provided at the inner peripheral surface of the fixed ring to provide communication between a protruding position cam groove portion of the first-cam-ring-movement cam groove and the recess. At the protruding position of the cam ring, a portion of the gear portion near the first cam follower passes through the release portion and is located inside the protruding position cam groove portion.

摘要： An engagement pawl of a linear-movement guide ring engages with an engagement groove of a cam ring, and hence the cam ring is supported by the linear-movement guide ring non-movably in an optical-axis direction. When the cam ring is rotated, a cam pin of a second group moving frame moves in the optical-axis direction along a cam groove formed in an inner periphery of the cam ring. The cam groove includes a plurality of first cam grooves and a plurality of second cam grooves. The engagement groove of the cam ring intersects with the second cam groove. The engagement pawl has a width larger than a groove width of the second cam groove intersecting with the engagement groove.
