Abstract
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.
