摘要： A collapsible lens barrel includes a first holding frame (2) for holding a first lens group (L1), a second holding frame (5) for holding a second lens group (L2) that is disposed on an image plane side with respect to the first lens group (L1), an actuator (6) for moving the second holding frame 5 in an optical axis direction, and a tubular cam frame (17) including a plurality of cam grooves that are formed at substantially equal intervals around a circumferential direction for moving the first holding frame (2) in the optical axis direction. The actuator (6) is attached to a portion in the cam frame (17) where the cam grooves are not formed. The first lens group (L1) is moved using the cam grooves, and the second lens group (L2) is moved using the actuator (6), so that a faster zooming speed and a lower zooming noise can be achieved.

摘要： A cam pin (16) and a demating prevention pin (35) that are provided in a driving frame (15) and have an identical shape are allowed to mate with a cam groove (18) and a demating prevention groove (36) that are provided in a cam frame (17), respectively. A first protrusion (37) is provided on at least one side in an optical axis direction of a portion of the demating prevention groove (36) with which the demating prevention pin (35) mates when the driving frame (15) is advanced. When an external force is applied to the driving frame (15), a cylindrical portion (35f) of the demating prevention pin (35) and the first protrusion (37) come into contact with each other. This prevents the cam pin (16) from demating from the cam groove (18). The cam pin (16) and the demating prevention pin (35) are made of common components, making it possible to reduce the number of components.
