BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention will be described below with reference to the drawings. In the following description, members corresponding to those described with reference to FIG. 4 will be assigned the same reference numerals and detailed description thereof will be omitted.

FIG. 1 is a plan view showing a connecting portion between a wisdom member and a temple member in an embodiment of an eyeglass frame of the present invention, and FIG. 2 is a view taken in the direction of arrow A in FIG. 1 and as described in FIG. The intelligence member 3 has one end fixedly fixed to the front frame 2 or the spectacle lens 1 and the other end rotatably connected to the temple member 4 by a hinge 7.

In the present embodiment, as the hinge 7, an outer piece member 8 having a U-shape in a side view and an inner piece member 9 inserted into the outer piece member 8 are connected by a connecting shaft 10 having a screw portion. It adopts a structure that is rotatably connected. In addition, hinge 7
The basic configuration of is not limited to that of this example.

The opposing ends 3a, 4a of the wisdom member 3 and the temple member 4 are slidably in contact with each other, and the opposing ends 3a, 4a have the same diameter, and the opposing end 3a side of the wisdom member 3 is a temple. The member 4 has an arc shape projecting toward the facing end 4a side, and the one end portion 9a of the inner piece member 9 of the hinge 7 is fixed to the facing end 3a portion of the wisdom member 3 and at the facing end 4a portion of the temple member 4. The one end 8a of the outer piece member 8 of the hinge 7 is fixed, and the other end 8b of the outer piece member 8 and the other end 9b of the inner piece member 9 are rotatably connected by a connecting shaft 10.

A plastically deformable recess 11 is formed at one end 9a of the inner piece member 9 which is fixed to the inner piece member 3, and a fixed portion of the inner piece member 9 of the inner piece member 9 is fixed.
A receiving groove 12 into which a part of the inner piece member 9 is fitted and brazed is formed.

In the embodiment having the above-described structure, the temple member 4 rotates about the connecting shaft 10 of the hinge 7 with respect to the wisdom member 3, just like a normal spectacle frame.

Here, the adjustment of the temple inclination angle in this embodiment will be described. Temple inclination angle θ is shown in FIG.
As shown in FIG. 3, the tilt angle of the temple member 4 with respect to the spectacle lens 1 or the front frame 2 is adjusted for each user. In this example, the concave portion 11 of the one end 9a fixed to the wisdom member 3 of the inner piece member 9 is plastically deformed in the up-down direction in FIG. 2 (for example, the two-dot chain line in FIG. 2) to make the wisdom member 3
The temple inclination angle θ can be easily adjusted by changing the attachment angle of the temple member 4 with respect to.

When the temple inclination angle θ is adjusted, the opposing ends 3a, 4a of the wisdom member 3 and the temple member 4 are arcuate concaves and convexes that slide with each other, so that the adjustment can be performed smoothly without any trouble. It can be performed, and of course, does not hinder the folding operation of both temple members 4.

It should be noted that in a spectacle frame, it is usually shown in FIG.
As shown in FIG. 2, when the temple members 4 are folded, it is preferable that the temple members 4 do not cross each other but linearly overlap each other, but in the present embodiment, the adjustment is performed. The temple member 4 is the intelligence member 3
However, since the connecting shaft 10 is displaced along with the movement of the temple member 4, when the temple member 4 is folded, as shown in FIG. It will overlap linearly.

As described above, even if the temple inclination angle is adjusted as described above, the original structure and function of the spectacle frame are not affected.

Further, in this embodiment, the receiving groove 12 into which a part of the inner piece member 9 is inserted is formed in the fixed portion of the inner piece member 9 on which the wisdom member 3 is fixed.
It is possible to firmly maintain the fixed state of the inner piece member 9 to the wisdom member 3, and it is possible to prevent the row from peeling off the inner piece member 9 from the wiping member 3.
