Abstract

　レンズホルダ(8)は、金属製のホルダ本体(12)と、被加工レンズ(7)の加工中心部(13)を保持する弾性部材(14)とで構成されている。ホルダ本体(12)は、前面中央に形成された嵌合孔(20)を有する。弾性部材(14)は、嵌合孔(20)に摺動可能に嵌合される嵌合軸部(14A)と、この嵌合軸部(14A)に一体に設けられたレンズ保持部(14B)とで構成される。レンズ保持部(14B)は、前面が被加工レンズ(7)を保持するレンズ保持面(24)を形成し、被加工レンズ(7)を保持する以前はホルダ本体(12)の前面(18)との間に適宜な隙間(g)が形成されており、被加工レンズ(7)に押し付けられると背面側に弾性変形してホルダ本体(12)の前面(18)に押し付けられる。
