Claims

[Scope of utility model registration request]

In the feeding mechanism of an optical pickup that reads information recorded on an optical disk by rotating a feed screw, the optical pickup has a corrugated surface on the opposite surface of the screw engaging part that is fixed to the optical pickup and receives the thrust of the feed screw. 1. A feeding mechanism for an optical pickup, characterized in that said waveform of a resin member, in which two parts are connected by a connecting portion with low rigidity, is constituted by a spring that presses the waveform into contact with a feeding screw.
