Abstract:
A lens holder (8) includes a metal holder main body (12) and an elastic member (14) which holds the processing center portion (13) of a processing target lens (7). The holder main body (12) has a fitting hole (20) formed at a front surface center. The elastic member (14) includes a fitting shaft portion (14A) to be slidably fitted in the fitting hole (20), and a lens holding portion (14B) integrally provided to the fitting shaft portion (14A). The front surface of the lens holding portion (14B) forms a lens holding surface (24) which holds the processing target lens (7). Before holding the processing target lens (7), a suitable gap (g) is formed between the front surface (18) of the holder main body (12) and the lens holding surface (24). When the lens holding surface (24) is urged against the processing target lens (7), the lens holding portion (14B) elastically deforms toward the rear surface and is urged against the front surface (18) of the holder main body (12).
