PURPOSE: To adjust an optical axis easily by bending a holder, to which a reflective mirror, etc. are attached, and a holder body, which is connected to this holder, in an information reader of an optical disc player to adjust the optical axis.

CONSTITUTION: A holder body 100, a pole brace 102, and a holder base 104 are formed into one body with flexible materials, and the holder body 100 is connected and supported to the holder base 104 through the pole brace 102. Two notched parts 114 are provided in accordance with two axes of a reflective mirror 112, and stress is concentrated to these parts 114 to bend the holder 108 and the holder body 100, thus adjusting the optical axis. Consequently, the adjusting operation is performed easily in a very short time. Further, since the whole of the holder 108 and the holder body 100 is bent with notched parts 114 as centers, deformation or the like is not generated in the attaching part of the reflective mirror 112, and it can be made small-sized.
