ビス金具に異常な力が作用する欠点があった。However, in the above-mentioned conventional metal fittings, when one of the two sets of insulators causes a cutting accident, the metal fittings and the clevis fittings strongly collide with each other. However, there is a drawback that an abnormal force acts on one of the insulator reams and the clevis fitting of the insulator ream.

４の鎖線参照）。[0005] Further description will be made with reference to Fig. 4. When the two insulator trains 2a and 2b are normal, the clevis fittings 3 and 3 are used.
Reference numeral 3 is attached to the metal fittings 10a and 10b at a predetermined normal mounting angle. However, since the insulator ream has a cement-welded portion due to its structure, the insulator ream may be cut though it is rare. For example, if the insulator ream 2b causes a cutting accident at a portion indicated by a cross mark in FIG. , Fittings 10a, 10b
It rotates about the installation parts a, a on the tower side and the electric wire side (see the chain line in FIG. 4).

ｂにおいても同様である。For this reason, a part of the clevis fitting 3 and the fittings 10a and 10b collide with each other, and an impact load of two to three times that of the normal state is applied to the other insulator row 2a. At the same time, an abnormal force acts on the collision portion between the clevis fitting 3 and the fitting 10a (see a in FIG. 4). FIG.
Shows only the metal fitting 10a, but the metal fitting 10a on the opposite side is shown.
The same applies to b.

Explaining based on FIG. 2 showing the left side metal fitting 1b in an enlarged manner, the mounting portions b, b of the pair of clevis metal fittings 3 , 3 are three.
Located a predetermined distance inside from both ends of the long side of the square shape
I have. And a mounting portion for the pair of clevis fittings 3, 3.
The portions of b and b opposite to the mounting portion are cut away, and cutout portions 5 and 5 are formed. The size of the cutout portion 5 is determined so that a predetermined thickness is provided around the mounting portion b so that the mounting portion b can maintain a predetermined strength. (See FIG. 2). In addition, both ends of the long side of the triangle shape
The holes shown in FIG. 4 respectively correspond to the conventional gold shown in FIG.
As shown also in the tool 1b, an application such as a wheel
