[Problems to be Solved by the Invention] However, 'as shown in FIG. 6, the above-mentioned conventional fixing yoke and the two U-shaped hook portions 11, 12 where the insulator string and the transmission line are installed are not on the same straight line, that is,' because In the deviated state, first, for example, when an electric wire is installed on the upper U-shaped hook portion 11, the yoke metal fitting γ 丨 there will be a prying movement in the ^]-shaped hook portion 丨, and the U-shaped hook portion 11 is destroyed. Or damage. As described in detail with reference to FIG. 7, the upper yoke and the U-shaped electric wire are first installed on the fixed yoke, but when the power transmission line is installed on the fixed yoke, the fixed vehicle is connected to the metal fitting 1 by the insulator string B. The pivoting part of 4 is centered on 4a, that is, 'the extension direction of the transmission line which is installed through the axis of the insulator string B and the connection metal fittings a becomes a straight line (refer to a point in FIG. 7, line). Since the yoke metal fitting γ 丨 rotates in the opening portion 1 of the 1-shaped hook 丨 丨 a to perform a prying movement, there is a risk that the yoke metal fitting γ ι may damage the U-shaped hook 11. Fig. 8 is the part of the above-mentioned Fig. 7 (: part enlarged view of the fitting and the U-shaped hook part 11 contact part, and the H-term pin p contact part. So, if the yoke metal fitting η in the mouth ^ rotation 'As shown by the black circle, the metal fittings γι hook portion 11 may be damaged, etc. In order to solve the above-mentioned lack of A α # 上, ^ supply, the purpose is especially in Ansuoyuan /// Fixed yoke.
