ABSTRACT:
An optical pickup has a support pedestal integrally formed at a rear end portion of a mounting surface of a base. A pair of left and right leg portions extend forwardly from both side edge portions of a rear end portion of a resilient plate. A fixing hole is penetratingly provided in each of the leg portions on a phantom line passing through a central axis of a photodiode and extending in a horizontal transverse direction. Each fixing screw is screwed into a threaded hole in the mounting surface through each fixing hole, so as to press the rear end portion of the resilient plate against the support pedestal.
