Abstract: An actuator is provided. In order to reduce the planar area of an actuator, a first magnetic drive circuit and a third magnetic drive circuit that vibrate a movable body in an X direction with respect to a support are provided respectively on both sides, in a Z direction, of a second magnetic drive circuit that vibrates the movable body in a Y direction with respect to the support. The movable ranges, in the X direction and the Y direction, of the movable body with respect to the support are regulated by a stopper mechanism constituted between a first magnet and a first coil holder holding a first coil, a stopper mechanism constituted between a second magnet and a second coil holder holding a second coil, and a stopper mechanism constituted between a third magnet and a third coil holder holding a third coil.

Abstract: A movable unit of an optical module having an image shake correction function is supported by a gimbal mechanism so as to be rotatable around a first axis R1 and a second axis R2. The movable body is driven by a shake-correction magnetic drive mechanism including magnets and fixed to the movable body. The movable body further includes a lens-moving magnetic drive mechanism to move a lens module in an optical axis direction. The lens-moving magnetic drive mechanism includes a lens-moving coil fixed to the lens module 7 and a lens-moving magnet disposed radially outward of the lens-moving coil. The magnets and also serve as the lens-moving magnet and are disposed radially outward of a triaxial intersection.

Abstract: A linear actuator may include a movable element; a stationary element; and a damper member inserted between a movable-element-side facing suface of the movable element and a stationary-element-side facing surface of the stationary element. The stationary element may include a first element structured to support the movable element via a spring member in such a way as to be movable, and a second element comprising the stationary-element-side facing surface and overlapping with the first element from a side opposite to the movable element in the moving direction. A distance adjusting part may be provided between the first element and the second element, the distance adjusting part being structured to adjust a distance between the first element and the second element in the moving direction, by way of deforming at least one of the first element and the second element.
