摘要： A lens barrel of the present invention includes a fixing frame 100 provided with cam grooves 103-105 formed in an inner circumferential surface of the fixing frame, and a drive frame 200 provided with cam followers 201-203 formed on an outer circumferential surface of the drive frame and a plurality of engaging teeth 200a provided to the outer circumferential surface of the drive frame so as to be located on substantially the same circumference as the cam followers 201-203. The drive frame 200 is adapted such that, with the drive frame incorporated in the fixing frame 100, the cam followers 201-203 are fitted in the cam grooves 103-105, drive force is transmitted via the engaging teeth 200a, and the drive frame 200 can move relative to the fixing frame 100 in the optical axis direction of a lens as the cam followers 201-203 move along the cam grooves 103-105. According to the present invention, it is possible to provide a lens barrel in which cam followers are less likely to come out of the cam grooves even in the case where a retainer wall cannot be provided within an area where a cam follower about to fall out is received directly by the wall, or in the case where the retainer wall provided within the area where a cam follower is received directly is not sufficient.
摘要翻译：本发明的镜筒包括：固定框架100，其设置有形成在固定框架的内周面上的凸轮槽103-105;以及驱动框架200，其设置有形成在所述固定框架的外周面上的凸轮从动件201〜驱动框架和设置在驱动框架的外周表面上的多个啮合齿200a，以便位于与凸轮从动件201-203基本相同的圆周上。驱动框架200适于使得当驱动框架结合在固定框架100中时，凸轮从动件201-203装配在凸轮槽103-105中，驱动力经由接合齿200a传递，并且驱动框架当凸轮从动件201-203沿着凸轮槽103-105移动时，200能够相对于固定框架100在透镜的光轴方向上移动。根据本发明，可以提供一种镜筒，其中凸轮从动件不太可能从凸轮槽中出来，即使在凸轮从动件即将脱落的区域内不能设置保持器壁的情况下直接由壁接收，或者在直接接收凸轮从动件的区域内设置的保持器壁的情况不足。

摘要： A lens barrel of the present invention includes: a fixing frame having a plurality of cam grooves that are formed an inner circumferential surface of the fixing frame and also having a protrusion provided between any adjacent two of the cam grooves among a plurality of the cam grooves; and a drive frame having cam followers that are provided to an outer circumferential surface of drive frame, are engaged with the cam grooves, and are movable along the cam grooves. With this configuration, when an external force is applied to the drive frame, an end portion of the drive frame comes into contact with the protrusion to prevent the cam followers from coming out of the cam grooves.
摘要翻译：本发明的镜筒包括：具有多个凸轮槽的固定框架，所述多个凸轮槽形成在所述固定框架的内周面上，并且在多个所述凸轮槽之间还具有设置在任何相邻的两个所述凸轮槽之间的突起 ; 并且具有设置在驱动框架的外周面的具有凸轮从动件的驱动框架与凸轮槽接合，并且可沿凸轮槽移动。利用这种构造，当驱动框架施加外力时，驱动框架的端部与突起接触，以防止凸轮从动件从凸轮槽中脱出。

The second support frame has an annular main body with a cam follower that extends outwardly in a radial direction. The cam follower is slidably disposed in the cam groove and has a first cam portion, a second cam portion and a connecting portion. The second cam portion is aligned with the first cam portion along the circumferential direction of the main body. The connecting portion connects the first cam portion and the second cam portion to create a space between the connecting portion and the cam groove.

摘要： A lens barrel (3) comprises a drive frame (30) and a first lens frame (50). The first lens frame (50) has first to third cam followers (54a to 54c) that are respectively inserted into first to third outer cam grooves (34a to 34c), and first and second auxiliary pins (55a and 55b) disposed so as to be able to come into contact with first and second auxiliary grooves (35a and 35b). When viewed in the Y axis direction, the first and second auxiliary pins (55a and 55b) are disposed between the first to third cam followers (54a to 54c) in the peripheral direction. The positions of the first and second auxiliary pins (55a and 55b) are offset from the positions of the first to third cam followers (54a to 54c) in the Y axis direction.
