VIBRATION-PROOF ACTUATOR, LENS UNIT WITH THE SAME, AND CAMERA

摘要

PROBLEM TO BE SOLVED: To provide a vibration proof actuator able to restrict magnetic force acting between driving magnets and a yoke, while avoiding a size increase.

SOLUTION: The vibration-proof actuator (10) for moving an image blur prevention lens (16) comprises: a fixing part (12); a movable part (14) to which the image blur prevention lens is attached; movable part support means (18) for supporting this movable part such that the movable part is able to move within a plane orthogonal to an optical axis; a plurality of driving coils (20) attached to one of the fixed part or movable part; a plurality of driving magnets (22) attached to the other of the fixed part or the movable part so as to face the corresponding drive coils; and one or more yokes (26) of the driving coils, which are arranged on the side not facing the driving magnets. The yoke is provided with magnetic force restraining cut parts (26a) in positions overlapping the driving coils, for restraining magnetic force received from these driving magnets.
