PURPOSE: An optical pick-up actuator is provided to restrict a tilt component by locating the center of spring coefficients to the driving center of a tracking coil, thereby making a lens holder move stably in the horizontal direction. CONSTITUTION: An optical pick-up actuator includes a lens holder in which an object lens is mounted, a movable unit, and a support. The movable unit is constructed in such a manner that a pair of tilting/focusing coils are arranged at both sides of the lens holder, and a tracking coil is located between the tilting/focusing coils. A yoke is placed opposite to the front face of the tilting/focusing coils and tracking coil. A magnet for generating a magnetic flux is attached to the inner side of the yoke. A fixed PCB is attached to a predetermined portion of each of both sides of the lens holder. The support has a damper holder for fixing and supporting 3-axis driving wires(61,63,65).
