PURPOSE: To prevent displacement at the time of bolt fastening, and improve working efficiency by forming one of the screw part of a bending back bolt end part arranged so as to cover a fastened material on a saddle as a right screw, and forming the other one as a left screw. CONSTITUTION: Fastened parts 4a, 4b are mounted on a saddle 2a when the fastened parts 4a, 4b are fixed, and a bending back bolt 1a is suspended so as to cover the fastened parts 4a, 4b. Both end parts of the bolt 1a is installed on the saddle 2a, the screw part 3a of the end part thereof is formed as a right screw, a screw part 3b is formed as a left screw, and thereby, the displacement of a fastened material fixing device is not caused even if both screw parts 3a, 3b are fastened simultaneously. It is thus possible to eliminate work for collecting displacement, and also improve work efficiency when the bolt 1a is fastened. When the bolt 1a is built into the saddle 2b, a drill hole which not have fine clearance and a notch 5 for fitting the fastened materials 4a, 4b are arranged. As a result, it is possible to improve working efficiency.
