Thus, when the eyeglasses (2000) to grab and rotate, the rotary cam 400 is fixed to the slide cam 300 is pushed upward while rotating. When the rotary cam 400 is further rotated so that the dead point 410 reaches the dead point 310 of the slide cam 300, as indicated by "A" in FIG. 4, the eyeglasses 2000 are in a worn position. Will be. In this wearing position (A), since no force is applied, the case where the head is pressed by the eyeglasses 2000 is not generated.

When the glasses leg 2000 is folded in order not to use the glasses in the wearing position A, the rotating cam 400 is rotated by the glasses leg 2000, and thus the slope 410 is the slide cam 300. The slope 310 is off. Accordingly, the glasses leg 2000 is rotated to the folded position B as shown in FIG. 4 by the shape of the cam and the elastic force of the elastic spring 200. In this case, since the glasses leg 2000 does not contact the glasses body 1000, the glasses lens or the like may be prevented from being damaged.

On the other hand, in the wearing position (A), by rotating the eyeglasses (2000) in the direction opposite to the folding direction is rotated to the position (C) to be fitted and fixed as shown in "C" in FIG. This rotation is the same as the above-described folding position (B), but only the rotation direction is made in reverse, the detailed description thereof will be omitted here.
