    • A coil spring (16) is held in a compressed state between a forward end side of an elastic member compartment of a temple (8) and a working face (26) of a cover (20). A plate spring (18) which is folded in two is held in a concave part (28) of the cover (20) so that a side closer to a base end portion of the temple (18) is open, with one of two open forward ends of the plate spring (18) engaged with a step (12) on a bottom surface of the elastic member compartment for preventing the cover (20) from being slid toward the base end portion of the temple (8) and slipping off. An outer end surface (20a) on a base end portion side of the cover (20) is in contact with a forward end surface (6a) of a rim (6) in a worn position. The cover (20) is pushed by the forward end surface (6a) of the rim (6) when the temple (8) is further spread beyond the normal position, to be slid toward the forward end along a guide member (14) of the temple (8) while compressing the coil spring (16) against its spring force.
    • 螺旋弹簧(16)被保持在压缩状态下,在一个镜腿(8)的弹性件隔室的前端侧和一个罩(20)的工作面(26)之间。 折叠成两个的板簧(18)被保持在盖(20)的凹部(28)中,使得靠近寺庙(18)的基端部的一侧打开,其中两个打开 与弹性构件隔室的底面上的台阶(12)接合的板簧(18)的前端部,用于防止罩(20)朝向镜腿(8)的基端部滑动而脱落。 盖(20)的基端部侧的外端面(20a)与磨损位置的轮辋(6)的前端面(6a)接触。 当镜腿(8)进一步展开超过正常位置时,盖(20)被轮辋(6)的前端表面(6a)推动,沿着导向件(14)向前端滑动 同时在克服其弹簧力的同时压缩螺旋弹簧(16)的同时(8)。
