PROBLEM TO BE SOLVED: To provide a connecting member, a tension material fixing tool, and a prestressed concrete structure having an excellent workability.SOLUTION: There is provided a connecting member connecting end parts of first tension material and second tension material arranged in the opposite direction each other, comprising a straight cylindrical part comprising a through hole in which, when a side where the first tension material is arranged is defined as a primary side and a side where the second tension material is arranged is defined as a secondary side, the first tension material is inserted and extends from an end part at the primary side to an end part at the secondary side, a curve cylindrical part comprising a through hole into which the second tension material is inserted and which has a curve from the end part at the secondary side to the end part at the primary side, and a connecting part which integrally connects the straight cylindrical part and the curve cylindrical part in an aligned manner. The straight cylindrical part comprises a first stress supporting part which supports with pressure a first socket onto which a cone shape first wedge for holding the end part of the first tension material onto the end part at the secondary side is fitted. The curve cylindrical part comprises a second stress supporting part which supports with pressure a second socket onto which a cone shape second wedge for holding the end part of the second tension material onto the end part at the primary side is fitted.SELECTED DRAWING: Figure 1 【課題】施工性に優れる接続部材、緊張材用定着具、及びプレストレストコンクリート構造物を提供する。【解決手段】互いに反対方向に布設される第一緊張材と第二緊張材の端部同士を接続する接続部材であって、第一緊張材が布設される側を一次側、第二緊張材が布設される側を二次側とするとき、第一緊張材が貫通されて一次側の端部から二次側の端部に向かって直進する貫通孔を有する直筒部と、第二緊張材が貫通されて二次側の端部から一次側の端部に向かって湾曲する貫通孔を有する湾曲筒部と、直筒部と湾曲筒部とを並列して一体に連結する連結部と、を備え、直筒部は、二次側の端部に第一緊張材の端部を把持する円錐状の第一ウェッジが嵌め込まれた第一ソケットを支圧する第一支圧部を備え、湾曲筒部は、一次側の端部に第二緊張材の端部を把持する円錐状の第二ウェッジが嵌め込まれた第二ソケットを支圧する第二支圧部を備える接続部材。【選択図】図１
