Abstract: A lens barrel in which a lens can be moved in a direction parallel to an optical axis includes: a first frame having a cam follower and a cam follower base that holds the cam follower; and a second frame that has a cam groove engageable with the cam follower. The first frame and the second frame are moved relatively to each other along the optical axis. The cam follower base has a first end connected to the main body of the first frame via at least one thin portion, and a second end not connected to the main body. The thin portion is formed such that a thickness of the thin portion in a radial direction of the lens barrel is smaller than that of the cam follower base.

The first restricting portion engages with the second restricting portion. The cam engages with the cam groove (1036). The drive arm moves approximately parallel to the optical axis due to the relative rotation of the second with respect to the first frame, the third is biased by the thus bringing the first contact portion and the second contact portion into contact with each other, and the third frame moves in the optical axis direction in an interlocking manner with the drive with the inclination of the guide being restricted by the guide.

Abstract: A lens barrel includes a first lens, a second lens, a first frame body, a second frame body, and a retracting lens frame. The retracting lens frame is configured to move so that a position of the second optical axis of the second lens changes from a position on the first optical axis of the first lens to a position that is outside the first optical axis, during the transition period between the imaging enabled state and the housed state. A contact portion is formed on the inner peripheral part of the first frame body. A protrusion of the retracting lens frame is configured to engage with and guided by the contact portion during movement of the retracting lens frame. The thickness of a region constituting the side wall of the contact portion is increased over the thickness of the other region toward the inside of the cylindrical part.

Abstract: An aperture unit comprises a base plate, a cover, a plurality of movable blades, a drive ring, a drive motor, and rotation shafts. The movable blades are disposed between the base plate and the cover, and adjust the amount of light passing through by varying the size of the opening by opening and closing operations. The drive ring is disposed between the base plate and the cover, is rotationally driven when the movable blades are opened and closed, and has a plurality of cam pins that move along cam grooves in the movable blades. The cover has protrusions that protrude toward the movable blades along the optical axis direction and restrict the movement of the movable blades in the optical axis direction.
