摘要： A lens barrel includes an operation member adapted to be movable to a first position and a second position and turnable at each of the positions, a turning member adapted to turnably engage with the operation member at the second position, and disengage from the operation member at the first position, a first detection unit adapted to detect a turning position of the turning member configured to turn in engagement with the operation member, a second detection unit adapted to detect a turning amount and a rotational direction of the operation member when the operation member is disengaged from the turning member, and a moving unit adapted to move the focusing lens along the optical axis based on an output from the first detection unit or the second detection unit.

摘要： A lens barrel has a first group frame provided with a rotating frame having a cam groove and made of a synthetic resin and a cam follower made of a synthetic resin integrated with the circumferential face for relative movement with the rotating frame and engaged with the cam groove, in which a shaft member made of metal is inserted into the center portion of the cam follower. If the lens barrel is dropped and the first group frame undergoes a relatively large impact force, the impact force acts between the cam groove and the cam follower, but since the shaft member is inserted into the cam follower as mentioned above, breakage of a root portion of the cam follower is prevented, and since the cam groove and the cam follower are both resin, plastic deformation on the cam groove side is also prevented.
摘要翻译：透镜镜筒具有第一组框架，该第一组框架设置有具有凸轮槽并由合成树脂制成的旋转框架，以及由与圆周面一体化的合成树脂制成的凸轮从动件，用于与旋转框架相对运动并与凸轮槽啮合，其中由金属制成的轴构件插入凸轮从动件的中心部分。如果镜筒落下并且第一组框架经受相对较大的冲击力，则冲击力作用在凸轮槽和凸轮从动件之间，但是由于轴构件如上所述插入到凸轮从动件中，所以根部的断裂防止了凸轮从动件的一部分，并且由于凸轮槽和凸轮从动件都是树脂，因此也防止了凸轮槽侧的塑性变形。
