Abstract:
An image stabilizer comprising:a movable member which supports an image-stabilizing optical system; a base which supports said movable member to be movable in a plane perpendicular to an optical axis of said image-stabilizing optical system; and at least three tilt prevention mechanisms, arranged on a circle centered on said optical axis, for preventing said image-stabilizing optical system from tilting at the time said image-stabilizing optical system reaches a movable limit position thereof in said plane perpendicular to said optical axis; wherein each of said at least three tilt prevention mechanisms comprises a conically-tapered annular convex surface and a conically-tapered annular concave surface having an axis extending parallel to said optical axis, said conically-tapered annular convex surface and said conically-tapered annular concave surface being correspondingly formed on one and the other of said movable member and said base, respectively, so that said conically-tapered annular convex surface contacts said conically-tapered annular concave surface when said movable member reaches said movable limit position.
