Abstract
PURPOSE:To prevent a stamper outer periphery press ring and a mold from getting scored by disposing a spring component between a fastening component to press and retain the stamper outer periphery press ring and the stamper outer periphery press ring. CONSTITUTION:A plurality of bolt holes 13 are formed at almost equal interval on a stamper outer periphery press ring 8 in the peripheral direction, and bolts 15 are inserted into the bolt holes 13, while coil springs 17 are disposed on the outer periphery of set pieces 16 inserted into shaft sections of the bolts 15. The inner face of the stamper outer periphery press ring 8 is formed into an inclined face with an inclination almost similar to the inclination of generating line of a truncated conical section of a fixed side of a mirror plate 1a, while an outer side section 8a can be slide freely with the truncated conical section 10. In case the stamper outer periphery press ring 8 is defectively mounted, the surface pressure to the truncated conical section gets high, and is pressed with the coil springs 17, and as a result, the stamper outer periphery press ring 8 is displaced in the direction to alleviate the surface pressure to correct its position.
