发明名称 SHAKE CORRECTION DEVICE AND OPTICAL DEVICE
摘要 PROBLEM TO BE SOLVED: To provide a shake correction device that can suppress rotation without providing a mechanical energization mechanism for suppressing the rotation on a movable side, and without providing a special outer peripheral shape changing a center of gravity of thrust of the shake correction device and a final position of a center of gravity of an absorption power, and to provide an optical device including the shake correction device.SOLUTION: A shake correction device comprises: first driving means that includes a movable holding member holding a shake correction element and being moved in a first direction and a second direction in an in-plane orthogonal to an optical axis, and a first counter yoke forming a first driving magnet on one of fixture holding members and a first coil and a magnetic path on the other thereof, and drives in the first direction; and second driving means that includes the movable holding member and a second counter yoke forming a second driving magnet on the one of fixture holding members and a second coil and the magnetic path on the other thereof and drives in the second direction. The first counter yoke and the second counter yoke respectively have an absorption centralization part at least at two points where absorption generated per one pole of the first driving magnet and the second driving magnet is centralized.
