PROBLEM TO BE SOLVED: To decrease the number of components and to reduce cost in a fastening fixture which improves work efficiency by regulating rotations of a fastening nut 30 and keeping an interval between a vibration preventive metal fitting 3 for fixing a fixture target to a groove-shaped rail 1 and the fastening nut 30, the fastening fixture being configured to attach the vibration preventive metal fitting 3 to the groove-shaped rail 1.SOLUTION: The fastening fixture comprises: the fastening nut member 30 including a rotation preventive member insertion part; and a rotation preventive member 20 including a guide part 22 which is inserted into the rotation preventive member insertion part of the fastening nut member 30 and with which a projection 23 is formed. A sliding action of the fastening nut member 30 along the guide part 22 with rotations of a screw member 10 in a fastening direction is temporarily stopped by the projection 23, and the interval between a metal fitting body and the fastening nut member is kept. When torque of rotating the screw in the fastening direction is further strengthened, a state of temporary stop by the projection 22 can be cancelled.SELECTED DRAWING: Figure 9 |
