Abstract: A lens barrel includes: a first ring; a second ring that switches between a first position and a second position by sliding in an optical axis direction; a plurality of biasing mechanisms that are provided on one of the first ring and the second ring, and providing adjustable biasing force in a radial direction; and a locking portion provided on the other of the first ring and the second ring on which the plurality of biasing mechanisms are not provided. The plurality of biasing mechanisms each include an elastic component having a contact portion and a biasing component that biases the elastic component. The first ring and the second ring are integrally rotatable when the contact portion contacts the locking portion which opposes the contact portion when the second ring is at the second position.

Abstract: A lens barrel includes a tip member, a lens hood, and a sliding member. The tip member is disposed on a subject side in an optical axis direction, and includes an optical system. The lens hood moves between a storage position and a use position in the optical axis direction. The sliding member is provided on an inner circumferential surface side of the lens hood. When the lens hood moves from the storage position to the use position, the sliding member moves to the subject side in the optical axis direction in a state where the sliding member is in contact with an outer circumferential surface of the tip member. In a state where the lens hood is located at the storage position, an interval of at least a portion of a clearance formed between the inner circumferential surface of the lens hood and the outer circumferential surface of the tip member is narrowed toward the subject side in the optical axis direction.

Abstract: An optical device actuator comprises a movable frame (33) including a focus lens (L11); a main shaft guide (40); a piezoelectric element (36a); a weight (36b); a fixed frame (30); a guide holding frame (35); and a spring (36c). The piezoelectric element (36a) imparts vibration to a first end (40a) side of the main shaft guide (40). The fixed frame (30) supports the piezoelectric element (36a) and the weight (36b) disposed on the first end (40a) side of the main shaft guide (40). The guide holding frame (35) supports, in a fixed state, the main shaft guide (40) on a second end (40b) side on the opposite side from the first end (40a) side. The spring (36c) is provided on the first end (40a) side of the main shaft guide (40), and presses the piezoelectric element (36a) along the axial direction with respect to the first end (40a) of the main shaft guide (40) via the weight (36b).

Abstract: A lens barrel includes: a first lens holding frame; a fixed barrel holding the first lens holding frame and including an elongated window provided radially; and a first step-type eccentric roller rotatably fixed to the first lens holding frame. The first step-type eccentric roller includes usable and non-usable regions on a periphery substantially perpendicular to the rotation axis, a distance from a center of the rotation axis to any point within any one of the usable regions is constant, and the distance is different for each of the usable regions, and the first step-type eccentric roller is fixed to the first lens holding frame by rotating the first step-type eccentric roller about the rotation axis, changing an engagement position between one of the usable regions and a side forming the polygonal shape of the elongated window, and moving the lens group parallel to an optical axis to perform shift adjustment.

Abstract: A lens barrel is detachably attached to a camera body, and includes an exterior unit, a rear frame, a tripod mount, and a tripod lock screw. The exterior unit includes an optical system. The rear frame is mounted to the exterior unit so as to be rotatable around an optical axis. An outer peripheral surface of the lens barrel is configured with the exterior unit and the rear frame. The tripod mount is provided on the rear frame to be fixed to a tripod. The tripod lock screw fixes a rotational position around the optical axis of the rear frame to the camera body at a predetermined rotational position, in a state in which the lens barrel is mounted to the camera body.
