ABSTRACT:
In an optical pickup including a supporting member for movably supporting a lens holder through a plurality of linear spring members, a holding member is provided between the lens holder and the supporting member and having holes for accommodating a plurality of linear spring members, and a damper gel is filled in the holes in the holding member for damping deflection of the linear spring member. Gaps are formed between the edge defining an opening of the hole on the holding member opened toward the supporting member and the supporting member, and the damper gel is not filled around the linear spring member at the closest position with respect to the optical disk but is filled around other linear spring members. Accordingly, when wiping off dirt attached to the objective lens, the damper gel is prevented from attaching on projections of the cleaner even when the projections pass through the gap formed between the holding member and the supporting member.
