Abstract:
A shake correction device may include a housing unit; a movable body; a fixed body; a swing support mechanism; a shake correction drive mechanism; and a posture return mechanism. The shake correction drive mechanism may include a magnet and a coil, the coil being configured to apply an electromagnetic force to the movable body. The posture return mechanism may include the magnet and a magnetic member, the magnetic member configured to urge the movable body toward the reference posture. The magnetic member may include a convex surface protruding, and the other body may include a radial positioning unit to press the convex surface of the magnetic member against the radial positioning unit by the attraction force to position the magnetic member in a direction orthogonal to the axial line. The radial positioning unit may include a concave surface with which the convex surface is contacted.
