A fitting structure for fitting a laser holder (2) holding a semiconductor laser (1) to a base member (3) in an optical pickup device includes a support member (5) of a metal plate that supports the laser holder (2). The support member (5) integrally has: a base part (6) having a laser passage hole that is formed in the center thereof for permitting laser light from the semiconductor laser (1) to pass therethrough; an upper projecting part (7) and a lower projecting part (8) that respectively project from the upper and the lower edges of the base part (6) so as to oppose each other and that support the laser holder (2) so that the laser holder (2) can swing about the vertical axis; and a bending part (9) that is elastically deformable and that first projects from the upper edge of the base part (6) toward a side opposite to a side toward which the upper projecting part projects and then is bent downward and also inward toward the base part (6). The base part (6) is inserted from the lower projecting part (8) along the plate-like fitting part (4) of the base member (3), whereby the plate-like fitting part (4) becomes sandwiched between the bending part (9) and the base part (6) by an elastic restoring force of the bending part (6), and then, after optical axis adjustment of the semiconductor laser (1), the laser holder (2), the support member (5), and the base member (3) are fixed to one another with an adhesive. |
