A thick ring 22 is rolled on the head side of the shaft 21a. The thick ring 22 has a V-shaped chevron shape, the tip side and the head side of the thick ring 22 are mirror-symmetrical, and have the same shape (slope with the same gradient). In this embodiment, four thick rings 22 are formed by rolling, and each of them is adjacent to each other with almost no gap. The diameter d of the thick ring 22 is smaller than the diameter D of the thread 21c.

る。The wood screw 21 is screwed up to the pillar 11 as in the first embodiment. After that, the thickness W of the heat insulating material 13 is adjusted. Since the shape of the thick ring 22 in the tightening direction (the tip side of the wood screw) and the shape in the loosening direction (the head side of the wood screw) have the same slope, the resistance in the tightening direction and the resistance in the loosening direction are different. The resistance is equal, and the resistance in the loosening direction is greater than that of the thin ring shown in FIG. In addition, since the tip side and the head side have the same inclination, damage to the wood fibers is reduced. Therefore, when the wood screw 21 is loosened, the thick ring 16 comes into close contact with the crosspiece 14 and pushes up the crosspiece 14 to reliably prevent the head 21b from jumping out.

緩くすることが望ましい。The same can be said for the embodiment of FIG. 3 as for the embodiment of FIG. That is, the thick ring 22 is most effective when the gradient in the tightening direction and the gradient in the loosening direction are equal to mirror symmetry, but is not necessarily required to be mirror-symmetric. The gradient in the tightening direction and the gradient in the loosening direction may be different. However, when making them different, it is desirable to reduce the gradient in the tightening direction.
