Abstract:
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.
