Claims

[Claims for Utility Model Registration] (1) An objective lens holder that is rotatably fitted to the central axis and slidable up and down, and a cylindrical focus coil fixed to the lower surface of the objective lens holder. , an optical pickup equipped with a tracking coil attached to the outer peripheral surface of the focus coil, and a damper for maintaining a neutral point that supports the objective lens holder via a support shaft fixed perpendicularly to the lower surface of the end of the objective lens holder. In the actuator for
An actuator for optical pickup, characterized in that a coil guide hole is formed in the support shaft passing through the axis, and wire harnesses for the focus coil and the tracking coil are guided to the upper surface side of the objective lens holder through the coil guide hole. (2) Utility model registration claim 1, characterized in that the wire harness passed through the coil guide hole is guided to the focus coil and tracking coil side through the coil guide groove formed on the upper surface of the objective lens holder. Actuator for optical pickup as described in section.
