Abstract
A spectacle frame which is low in height when folded, which is made up of a smaller number of parts and can be assembled efficiently at a low cost. Each auxiliary temple is connected to a mounting piece fixed to a lens frame so that it can be folded downward from the position in which it extends rearwardly from the mounting piece. When it is bent downward, it is resiliently urged upward. A main temple is connected to the rear end of each auxiliary temple so that it can be bend downward from the position in which it extends rearward from the auxiliary temple. Each auxiliary temple houses mechanisms for keeping the auxiliary temple in a predetermined position relative to the mounting piece and for keeping the main temple in a predetermined position relative to the auxiliary temple. It is thus possible to use the same parts for both these mechanisms and thus to reduce the number of parts of the entire spectacles.
