Abstract
The present invention provides a shake correction device which can not generate the hysteresis phenomenon and can suppress unnecessary resonance and improve endurance with respect to drop impact. In this shake correction device, the eddy current induction plateof +Z side is opposite to and has a gap with the surface () of the +Z side of the permanent magnet () which is arranged to wind around the optical axis at an interval of 90 degree in the Z direction, the eddy current induction plateof radial direction is opposite to and has a space with the surface () of the outside in the radial direction, and the eddy current induction plateof the periphery direction is opposite to and has a gap with the surface () in the periphery direction.
