PROBLEM TO BE SOLVED: To provide an optical pickup device, in which the grating adjustment can be performed with a simple structure and an optical part housing module. SOLUTION: A circular arc-shaped projection 49 formed on one side face of the optical housing module 70 integrally housing first and second light emitting elements 41 and 42, a grating 43, a light receiving element 57, etc., is mounted to the circular arc supporting part 82a of a carriage body 80 and an annular guide part 50 formed on the extension of the axis of the projection 49 is mounted to a bowl-state supporting part 82b. Thus, an abutting face 52 formed at a position deviated from the axis is moved by a slide-cam member 62 to realize grating adjustment with the axis of a module 70 as the center. |
