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.

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: Lens barrel includes first group lens frame unit, second group lens frame unit, lens frame, insertion hole, and depressions. First group lens frame unit holds lenses. Second group lens frame unit holds lens. Lens frame is disposed between first group lens frame unit and second group lens frame unit on an inner circumference side of first group lens frame unit through radial clearance. Insertion hole is provided on an outer peripheral surface of first group lens frame unit, and a jig of lens frame is inserted into insertion hole. Depressions are provided at a position accessible from an outside in a state where first group, second group lens frame units and lens frame are assembled, and fix lens frame to first group lens frame unit.
