<p>This invention relates to glasses, and more particularly to glasses produced by using an NT alloy. A spectacle frame in which swivel stop grooves (12) are formed at the ends of joint members and locking cylinders (13), which have threads in the inner surface thereof, are fixed firmly over the grooves (12). The resultant products are joined to locking parts (8), (9) of the rims (2) to be set with fixing means. A bridge and a span for the spectacle frame having such a construction are connected to the rims with screws via the locking cylinders. Since this spectale frame has such a construction, various types of parts may be prepared in advance so that they can be exchanged easily in accordance with a user's request.</p> |
