ABSTRACT:
An objective lens posture adjusting mechanism of an optical pickup capable of easily adjusting the objective lens posture. In order to adjust an inclination angle of an objective lens about two axes relative to an optical system support base, an intermediate base is superposed upon the optical system support base via first cylindrical surfaces, an object lens support base is superposed upon the intermediate base via second cylindrical surfaces having a center axis not parallel to a center axis of the first cylindrical surfaces, and the inclination angle of the objective lens about the two axes is adjusted by relative rotations of the first and second cylindrical surfaces.
