摘要： A pivotable mirror device for tracking and for driving a light beam spot in the radial direction of an optical disk includes a mirror holder holding a reflecting mirror pivotably supported by a thin leaf spring. A planar portion of the thin leaf spring is laid on the reflecting surface of the reflecting mirror. The thin leaf spring is constricted between the planar portion and a portion in which the thin leaf spring is attached to a thin leaf spring supporting member to thereby form a torsional portion for pivotal movement thereof. A high attenuation member is attached to the torsional portion.
