<p>In an optical head of an optical recording and reproducing device for optically recording or reproducing informations, when a holder (3), which is provided with an optical element fixedly disposed thereon, is fixed to a housing member (1), the holder (3) is housed in a guide hole (2) of the housing member (1) and then a screw (4) is screwed into a tapped hole (5) formed in the housing member (1) not so as to reach the guide hole (2) to press a bottom portion of the tapped hole against the holder (3). Accordingly, with the optical head according to the present invention, a torque of rotation generated when the screw (4) is rotated is absorbed in the bottom portion of the tapped hole (5), so that the holder (3) is not moved when the screw (4) is screwed into the tapped hole (5), whereby the optical element fixedly disposed on the holder (3) can be easily positioned at an appointed position.</p> |
