Abstract: <P>PROBLEM TO BE SOLVED: To correct a tilt with favorable follow-up ability to be able to cope with high integration by a simple configuration without burdening a movable part having an objective lens or the like with a load.  <P>SOLUTION: The correction of a tangential tilt of the objective lens 2 is made possible by relatively displacing other side ends of wire springs 4a-4b fixed to the fixing part sides so that the wire springs 4a, 4b arranged at positions differing in directions of fuci and wire springs 4c, 4d are offset from each other in their longitudinal directions, and thereby rotatively displacing the movable part 9 sides supported by one-end sides of the wire springs 4a-4d. For this purpose, the ends on the other sides of the wire springs 4a-4d have only to be fixed movable and provided with its tilt correction driving source, and this arrangement can be obtained without burdening the movable part 8 with a load. Moreover, since longitudinal displacements of the wire springs are utilized, tangential tilt correction in which the movable part 8 side has favorable follow-up ability responsive to a high speed operation becomes possible.  <P>COPYRIGHT: (C)2004,JPO
