Abstract
A turning mechanism of a temple with respect to a bracket capable of always keeping the resistance force relative to the turning of the temple T with respect to the bracket and of regulating the resistance force. The turning mechanism comprises a shaft supporting portion provided on the bracket and having a hollow hole section therein, a shaft portion provided on the temple and having a hollow hole section therein, and an expansion member, wherein the expansion member is press-fitted in the hollow hole section of the shaft portion in a state where the shaft portion is fitted in the shaft supporting portion to produce a friction force due to a pressing force of the expansion member, thereby applying a resistance force against the turning of the temple.
