Abstract
A lens barrel includes a first support frame and a second support frame. The first support frame has a cam groove. 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.
