待できる。In FIG. 4, the effect of locking can be exhibited by the difference between the pitch p 1 of the standard complete male thread portion and the pitch p 2 of the dependent complete male thread portion when tightening the loosening machine screw 1 of the spectacle frame. Since p 1 > p 2 in the prior invention, the hinge 7 of the spectacle frame tries to open outward, and the degree of opening / closing of the temple 8 becomes looser as the tightening screw 1 is tightened. The opening and closing condition cannot be adjusted. Since p 1 <p 2 in the present invention, the hinge 7 of the spectacle frame tends to close inward, and thus the degree of opening of the temple 8 becomes stiff. Therefore, the degree of tightening of the loosening prevention small screw causes the temple 8 to be closed. Opening and closing can be adjusted, and in addition to the effect of preventing loosening of the screw by the loosening small screw 1 of the spectacle frame, the effect of being able to maintain the opening and closing condition of the temple 8 constant for a long period of time can be expected.
