Optical pickup

An optical pickup comprising a base member mounted astride a main shaft and a secondary shaft with the travel thereof being adapted to be guided by said main shaft on which a printed circuit board with a control element as a heating part mounted thereon and a radiator plate for suppressing fever in said control element are mounted, in which a secondary bearing part adapted to slide relative to said secondary shaft comprises an overlapping sliding face slidably overlapping said secondary shaft and an auxiliary overlapping face forming a clearance with said secondary shaft on the opposite side of said overlapping sliding face with respect to said secondary shaft, wherein

• said radiator plate has:
• an overlapping portion overlapping said control element that is positioned in the vicinity of said secondary shaft;
• a contact piece overlapping said secondary bearing part that is made of metal;
• and a pressing piece comprising a plate-like suspended piece portion formed at the end edge on the side of said secondary shaft in a bent manner to extend through the inside of said secondary shaft and a main piece portion formed at the end edge of said suspended piece portion in a bent manner to be in elastic contact with said secondary shaft to bring said overlapping sliding face of said secondary bearing part into elastic contact with said secondary shaft, said pressing piece being arranged laterally adjacent to said secondary bearing part, and a cable pulled out of said printed circuit board being held by said suspended piece portion of said pressing piece to be kept away from said secondary shaft.
