軸孔１０が形成されている。BACKGROUND ART FIG. 4 is an exploded front view of a prior art hinge 1 for eyeglasses, and FIG. 5 is a bottom view of the hinge 1 for eyeglasses. The hinge 1 for eyeglasses will be explained using FIGS. 4 and 5. The hinge piece 2 includes heads 3 and 4 facing each other with a notch in between. The head 3 is formed with a shaft hole 6 through which the hinge shaft 5 is inserted, and the head 4 is formed with a shaft hole 7 having an internal thread into which the hinge shaft 5 is screwed. The hinge piece 8 includes a protrusion 9 that is inserted into the notch of the hinge piece 2 and contacts the heads 3 and 4 with a slight gap between them. A shaft hole 10 is formed in the protrusion 9 and is coaxial with the shaft holes 6 and 7 when the hinge pieces 2 and 8 are combined.
