摘要： A lens barrel includes: a holding frame; a cam ring rotatable relative to the holding frame around a rotational axis substantially parallel to an optical axis of an imaging optical lens system; and a cam follower and a cam groove that engage with each other so that the holding frame and the cam ring move relative to each other along the optical axis when the holding frame and the cam ring are rotated relative to each other.
摘要翻译： 镜筒包括：保持框架; 凸轮环围绕基本上平行于成像光学透镜系统的光轴的旋转轴线相对于保持框架旋转; 以及当保持框架和凸轮环相对于彼此旋转时彼此接合的凸轮从动件和凸轮槽，使得保持框架和凸轮环沿着光轴相对于彼此移动。

摘要： There is disclosed a lens barrel including a fixed frame, a rotary frame rotatable with respect to the fixed frame to advance or retract in an optical axis direction, and a rectilinear guide frame rotatable relative to the rotary frame to displace integrally with the rotary frame in the optical axis direction. In this structure, a front end portion of the rectilinear guide frame on a subject side in the optical axis direction is exposed from the rotary frame.
