Since the movable side mirror surface 4 is joined only by the inner peripheral stamper retainer 9 and the outer peripheral stamper retainer ring 10, the stamper 6 does not come into close contact with the movable mirror surface 4 and floats, causing the injected resin to cool and solidify or not.

題があった。In other words, the stamper is attached to the mirror surface on the movable side, but
Since the injected molten resin repeatedly expands and contracts due to the heat, the outer periphery of the stamper is usually not completely pressed down, and the entire stamper is not in close contact with the mirror surface on the movable side. For this reason, when the molten resin is cooled and solidified in the molding process, the stamper separates from the mirror surface on the movable side, causing uneven shrinkage of the molded product, which tends to cause molding defects such as sink marks and optical distortion (birefringence). Ta.
