Image stabilizing apparatus, lens barrel, and optical apparatus

摘要

An image stabilizing apparatus includes a shift member holding a lens, a first driver moving the shift member in a first direction in a plane orthogonal to an optical axis, and a second driver moving the shift member in a second direction in the plane orthogonal to the optical axis. The first driver includes a first magnet, a first coil, and a first yoke in order in an optical axis direction, the second driver includes a second magnet, a second coil, and a second yoke in order in the optical axis direction, the first yoke has a protrusion that protrudes in the first direction at least one of end portions extending in a direction orthogonal to the first direction, and the second yoke has a protrusion that protrudes in the second direction at least one of end portions extending in a direction orthogonal to the second direction.

1. An image stabilizing apparatus comprising:
a shift member configured to hold a lens; a first driver configured to move the shift member along a first direction along a plane orthogonal to an optical axis with respect to a body; and a second driver configured to move the shift member along a second direction that is perpendicular to the first direction along the plane orthogonal to the optical axis with respect to the body, wherein the first driver has a first magnet, a first coil, and a first yoke disposed in this order along an optical axis direction, wherein the second driver has a second magnet, a second coil, and a second yoke disposed in this order along the optical axis direction, wherein the first and second magnets are attached to one of the shift member or the body, and the first and second yokes are attached to the other of the shift member or the body, the first and second magnets being movable relative to the first and second yokes, respectively, wherein the first yoke has a first protrusion that protrudes along the first direction from at least one of two opposing sides thereof extending along the second direction, wherein the second yoke has a second protrusion that protrudes along the second direction from at least one of two opposing sides thereof extending along the first direction, wherein a width along the second direction of the first protrusion is smaller than a width along the second direction of the other of the two opposing sides of the first yoke, wherein a width along the first direction of the second protrusion is smaller than a width along the first direction of the other of the two opposing sides of the second yoke, wherein a length along the first direction of the first magnet is smaller than a length along the first direction between the two opposing sides of the first yoke, and wherein a length along the second direction of the second magnet is smaller than a length along the second direction between the two opposing sides of the second yoke.
