PROBLEM TO BE SOLVED: To prevent decline of tensile force of a composite strand accompanying the rotation of a holding body thereof, for a fixing device of the composite strand.SOLUTION: A pair of bolts 12b are screwed into a bottom surface of a holding body 12, a pair of insertion holes 2b are formed on a bearing plate 2, and in the state of abutting the holding body 12 to the bearing plate 2, the bolts 12b are inserted to the insertion holes 2b. Even when a composite strand 1 is to be untwisted by plastic strain generated accompanying compressive yielding of an inner layer wire 1a, since the holding body 12 is detained with respect to the bearing plate 2 by the bolts 12b, the untwisting is blocked and decline of tensile force is prevented. |
