Claims

[Scope of Claim for Utility Model Registration] A structure for fixing an optical component to a case, which includes a mounting surface formed at a location on the case where the optical component is fixed, and a mounting surface formed at a location on the case where the optical component is fixed. bulges formed at positions located at both ends of the optical component; an inclined surface formed on the bulge; an inclined surface formed at each end of the optical component so as to engage with the inclined surface when the optical component is placed on the mounting surface; and a case. A fixing structure for an optical component, comprising: a positioning means for positioning the optical component in a direction perpendicular to a direction connecting the two ends of the optical component.
