Claims

[Scope of utility model registration request]

a spherical support mechanism that tiltably supports an actuator having an objective lens on the optical pickup body; a fixing screw and an adjustment screw screwed onto the actuator through the optical pickup body;
A fixing coil spring is wound around a fixing screw and provided between the lower surface of the screw head and the optical pickup body, and an adjusting coil spring is wound around an adjustment screw and provided between the actuator and the optical pickup body. In the actuator tilt adjustment device, the actuator includes a coiled end of the fixing coil spring in contact with a portion of the actuator, a lower surface of the screw head of the fixing screw, an actuator in contact with the adjusting coil spring, and a light. Adjusting the inclination of an actuator characterized in that at least one part of the pick-up main body, the lower surface of the screw head of the adjustment screw, and the part of the optical pick-up main body with which it comes in contact is formed into a protruding shape to prevent galling. Device.
