The present invention proposes a screw-less hinge for spectacles using a single metal material for the entire set of spectacles excluding some spectacles parts, such as lenses, engagement rods, and nose pads, the hinge having a mechanism for allowing each temple to turn with respect to a corresponding lug and preventing play of the temple, in both an opened state and a closed state. The temple and the lug are both formed of a wire-like metal material. An end of the temple is formed into an annular shape so as to define a pivot hole. A pivot portion of the lug formed through bending the wire-like material of the lug is inserted into the pivot hole whereby turning motion of the temple is enabled. The lug is extended from the pivot portion along the temple and is bent so that a distal end portion of the lug is located on the inner side of the opened temple, to thereby form a temple-open-state holding portion for preventing the opened temple from turning inward. <IMAGE> |
