  • Patent number: 5760869
    Abstract: A coil spring is held in a compressed state between a forward end side of an elastic member compartment of a temple and a working face of a cover. A plate spring which is folded in two is held in a concave part of the cover so that a side closer to a base end portion of the temple is open, with one of two open forward ends of the plate spring engaged with a step on a bottom surface of the elastic member compartment for preventing the cover from being slid toward the base end portion of the temple and slipping off. An outer end surface on a base end portion side of the cover is in contact with a forward end surface of a rim in a normal use position. The cover is pushed by the forward end surface of the rim when the temple is further spread beyond the normal use position, to be slid toward the forward end along a guide member of the temple while compressing the coil spring against its spring force.
