Abstract: A lens barrel includes at least one lens, the optical axis of the lens; the first frame (the fixed frame 900) having the first restricting portion (901, 902) and having an approximately cylindrical shape about the optical axis; the second frame (1000) having the cam groove (1036) and having an approximately cylindrical shape about the optical axis; the third frame (510) having the guide portion (511) which restricts inclination thereof with respect to the first contact portion (514) and the optical axis and having an approximately cylindrical shape about the optical axis; the drive arm (520) having a cam follower (523), the second restricting portion (524, 525) and the second contact portion (526), and having an approximately arcuate shape constituted of a portion of a circular cylinder about the optical axis or an approximately plate shape; the guide shaft (601) for guiding the guide in a movable manner in the optical axis direction; and the spring (603). 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: An aperture unit includes a base plate, a cover, a plurality of aperture blades, a drive ring, and protrusions. The aperture blades are disposed between the base plate and the cover, and adjust the amount of light passing through by varying the size of an opening. The drive ring is disposed between the base plate and the cover, and is rotationally driven when the aperture blades are opened and closed. The protrusions are provided to the drive ring and the cover, respectively, and support the aperture blades in the direction of suppressing upward warpage of the aperture blades in a state in which the aperture blades move in the direction of reducing the size of the opening.

Abstract: A lens barrel includes a first frame body, a second frame body, a support frame, and a retracting lens frame. The support frame is supported by the second frame body and moves with respect to the second frame body within a first plane for image blur correction in an imaging enabled state, the first plane being perpendicular to an optical axis. The retracting lens frame moves around a retraction shaft during a transition period between an imaging enabled state and a housed state, the retraction shaft being substantially parallel to the optical axis. The support frame has a protrusion which comes into contact with a groove included in the first frame body and restricts a movable range of the support frame in the first plane and a second plane that is parallel to the first plane.

Abstract: The lens barrel includes a first planar portion, a barrier front cover, a vane portion, and a lens group frame. The first planar portion is configured to be substantially perpendicular to an optical axis and includes a first opening portion. The barrier front cover includes a second opening portion. The vane portion is configured to move between a first position and a second position. The vane portion is configured to cover the first opening portion and the second opening portion at the first position, and allow the first opening portion and the second opening portion to open at the second position. The lens group frame is configured to support rotatably the vane portion and includes at least one lens. The first planar portion is disposed closer to a subject than the barrier front cover. The first opening portion is formed smaller than the second opening portion.

Abstract: A lens barrel according to a first aspect of the present disclosure includes the lens frame which holds the lens, and the holding frame which holds the lens frame in a state where the lens frame is movable in a plane orthogonal to the optical axis. A biasing means which generates a force in the direction that the lens frame is lifted up against the gravity is provided to at least the holding frame out of the holding frame and the lens.
