<p>PROBLEM TO BE SOLVED: To eliminate such a problem that a rod is deformed oddly as seen in the conventional method, and increase the workability in installation by using, for collars formed along the short diameter sides of a cable having an elliptical cross section, a molded wire material which is formed in such a shape that it may be the thickest at the center, and may become gradually thinner towards the right and the left end viewed in a cross section. SOLUTION: Collars 14 formed at the short diameter sides of a cable 13 having an elliptical cross section are molded bodies which have a nearly elliptical cross section and are thickest at the center and become gradually thinner to the right and the left end. The molded bodies having a nearly elliptical cross section are made by arranging wires as a skeletal structure and then molding them with heat-resisting resin into an integral unit. The molded body is formed in such as shape that it may be the thickest at the center and becomes gradually thinner towards the right and the left end. By installing the collars 14 made by molding wires with the heat-resisting resin into one unit, the cross-sectional shape of the cable 13 is changed from elliptical to circular and thereby the cable can be stably gripped by a clamp. The wires corresponding to a rod are molded with heat-resisting resin into an integral unit, and therefore the odd deformation of the rod as in the conventional method is prevented and the installation time can be shortened.</p> |
