Abstract:
1. An optical pickup comprising: an objective lens for converging a light beam on an optical disk; a lens holder for holding the objective lens; a plurality of linear spring members fixed at one end to the lens holder and fixed at the other end to a supporting member for supporting the lens holder so as to be capable of moving at least in the direction of the optical axis of the objective lens with respect to the supporting member, a holding member provided between the lens holder and the supporting member, the holding member including holes through which the linear spring members are inserted; and a damper gel surrounding the linear spring members to damp deflection of the linear spring members, the damper gel being held in the holes, wherein the plurality of linear spring members are disposed in parallel at intervals in the direction of the optical axis of the objective lens, a gap is formed between the edge defining the opening of the hole opened toward the supporting member and the supporting member, and the damper gel does not fill the portion of the gap around the linear spring member at the closest position with respect to the optical disk but is filled around other linear spring members within the gap.
