Patent ID: 7907837

Claim:
An image blur correction apparatus, comprising: a movable member retaining one of an image stabilization optical element movable in a direction orthogonal to an optical axis and an image pickup element movable in the direction orthogonal to the optical axis; a ball positioning the movable member in an optical axis direction; a fixed member positioning the ball in the optical axis direction; a drive unit provided with a magnet for driving provided on one of the movable member and the fixed member, and with a coil and a magnetic member provided on the other of the movable member and the fixed member, and a restriction portion provided on the fixed member, wherein the movable member is retained at a center by an attraction force of the magnet for driving, and regulates, at a time of its movement, rotation in a plane orthogonal to the optical axis by the attraction force of the magnet for driving to a rotation angle equal to or smaller than a first rotation angle, wherein the restriction member is abutted to the movable member so that the rotation of the movable member in the plane orthogonal to the optical axis is regulated by a second rotation angle, and wherein the first rotation angle is smaller than the second rotation angle.
