ABSTRACT:
A polygon mirror is made by resin-forming and includes, at least on its referential surface for attachment, one or more kinds of elements selected from projections, hollow portions and through-holes. The hollow portions or through-holes are filled with an adhesive in contact with the referential surface for attachment. When only projections are used, pairs of projections are formed at corresponding positions on both the referential surface for attachment and the clamping member-receiving surface. When the polygon mirror is provided with projections in combination with hollow portions or through-holes, the projections penetrate through the respective hollow portions or through-holes.
