Abstract: A lens apparatus includes a lens holding member holding a lens, a first movement member, a guide member having a straight groove, a second movement member, a biasing member, and a cam member that has a cam groove and rotates relative to the guide member. The first movement member holds the lens holding member and moves in an optical-axis direction together with the lens holding member. The first movement member includes a cam follower that engages with the straight groove and the cam groove and that moves in the optical-axis direction by relative rotation of the cam member to the guide member. The second movement member moves in the optical-axis direction together with the lens holding member and the first movement member. The biasing member biases the lens holding member to the second movement member so that the cam follower is biased to the straight groove and the cam groove.

Abstract: A lens apparatus includes an imaging optical system, a movable member that holds at least one lens and is movable in a direction including component perpendicular to an optical axis of the imaging optical system, a coil, a first magnet, and a shield member that covers at least a portion of the coil viewed in an optical axis direction from an image plane side, covers at least a portion of the coil viewed in a first direction perpendicular to the optical axis from one side of the movable member, and covers at least a portion of the coil viewed in the first direction from the other side of the movable member.

Abstract: An image stabilization apparatus includes a fixing member, a movable member, a guiding member movable in a first direction orthogonal to the optical axis relative to the fixed member, and configured to guide the movable member while restricting a rotation of the movable member on the plane orthogonal to the optical axis relative to the fixed member, and a rolling member rollably held between the fixed member and the guiding member. The fixing member includes a first groove extending in the first direction and contacts the rolling member. The guiding member includes a second groove that extends in the first direction and contacts the rolling member. The rolling member can contact an end of the first groove and an end of the second groove while the guiding member is located at one of ends in a movable range of the guiding member in the first direction.

Abstract: An image stabilization apparatus includes a fixed member, a lens, a movable member, a guide member, and first to third rolling members. At least one of the fixed member, the movable member, and the guide member includes a movement restrictor configured to restrict a moving range of a restricted rolling member as at least one of the first to third rolling members in a predetermined direction on the plane perpendicular to the optical axis. The movement restrictor is formed such that as the restricted rolling member approaches to an end portion of the moving range, a center of the restricted rolling member approaches to a centerline in a width direction perpendicular to the predetermined direction of the movement restrictor.

Abstract: An image stabilization apparatus includes a fixed member, a movable member configured to hold an image stabilization lens and movable relative to the fixed member on a plane perpendicular to an optical axis of the image stabilization lens, a lock member that is disposed on an outer circumference side of the movable member and can be positioned at a lock position for restricting a movement of the movable member and an unlock position for enabling the movement of the movable member, and a retaining member configured to fix the movable member in an eccentric state when the lock member is located at the lock position.

Abstract: An image stabilization apparatus includes a movable member configured to hold an image stabilization optical element, a fixed member holding the movable member movably in a direction crossing an optical axis, an electrical element mounted on the movable member, and a flexible sheet member electrically connecting the electric element to the fixed member. The flexible sheet member is fixed to the movable member and the fixed member so that the flexible sheet member is bent between the movable member and the fixed member.
