PROBLEM TO BE SOLVED: To keep a spring constant of each wire rod constant by suppressing variations in front face shape of a damper material for suppressing a resonance of the wire rod in an optical pickup equipped with an actuator with which a movable side lens holder is supported in the shape of cantilever with two or more wire rods which are extended from a fixed side support member. SOLUTION: The wire rod 6 passes through the inside of a layer of a damper material 8 loaded in a space 7 provided in a fixed side support member 2. The space 7 is formed by a groove shaped blank space and in the front part of the groove shaped blank space, an aperture 77 surrounded by the groove shape surface 71 and columnar section 76 is equipped. The damper material 8 loaded in the space 7 is closely contacted with the groove shape surface 71 and the columnar section 76 within the aperture 77. COPYRIGHT: (C)2006,JPO&NCIPI
