However, in such a connection structure, the degree of freedom of the steel cable 1 relative to the metal fitting 2 is extremely small, causing various mechanical problems. Specifically, when the steel cable 1 is bent with respect to the metal fitting 2, the steel cable 1 is strongly bent at the welded portions 6, 6, and bending stress is concentrated there. As a result, when the steel cable 1 is used under conditions where it can be bent before and after the metal fitting 2, damage such as breakage of the steel cable 1 and cracking of the welded parts 6, 6 is likely to occur. Furthermore, when the steel cable 1 is used in an environment with severe temperature changes, there may be a temperature difference between the steel cable 1 and the metal fitting 2 due to structural problems, or if the steel cable 1 is made of different metals with different coefficients of thermal expansion. A thermal stress is generated between the welded parts 6 due to the difference in coefficient of thermal expansion that occurs when the welded parts 6 are in contact with each other. As a result, the same trouble as described above also occurs.

設されている。 In the connecting portion according to this invention, a metal fitting 12 as shown in FIG. 1 is used. The illustrated metal fitting 12 has a hollow cylindrical shape, and a through hole 15 provided on the central axis is open at both ends of the metal fitting 12. The diameter of the through hole 15 is slightly larger than the diameter of the steel cable 11 such as a wire, and the openings 16, 16 are opened sufficiently wider than the diameter of the steel cable 11. 15 is continuous by a smooth curved surface. In addition, a through hole 17 is formed in this metal fitting, extending from the outer circumferential side thereof to the through hole 15.
そして第２図で示すように、この金具１２に

近に設けるのが望ましい。 The shape of the metal fitting 12 may be cylindrical as described above, or
Various shapes, such as a prismatic shape, are adopted depending on the purpose of use. In addition, the welding holes 17 are not only required at one location, but for example, two are required facing each other across the through-hole 15, or three to six through-holes are required radially around the through-hole 15. A plurality of them can be provided depending on the welding strength and the like. Note that it is desirable to provide these through holes 17 as close to the center of the metal fitting 12 as possible.

In this connection part, the steel cable 11 and the metal fitting 12 are connected to the metal fitting 1.
2, and since the openings 16, 16 of the through hole 15 are sufficiently wide compared to the diameter of the steel cable 11, the steel cable 11 can move freely to some extent at both ends of the metal fitting 12. be able to. Therefore, even if the steel cable 11 is bent with respect to the metal fitting 12, bending stress is not concentrated in one place.
