PROBLEM TO BE SOLVED: To provide a fixture capable of easily being loosened whatever type of tools may be used.SOLUTION: This fixture 1 comprises a coil spring body 2, a nut body 3 and a metal fitting 30. The coil spring body 2 has a first coil spring part 2A, an end region 21 and a second coil spring part 2B. The end region 21 is an area of a coil element wire extending from one end of the coil element wire in the first coil spring part 2A and arranged outside the first coil spring part 2A. The second coil spring part 2B extends from the other end of the coil element wire constituting the first coil spring part 2A. The coil element wire constituting the second coil spring part 2B is wound in a larger winding diameter than that of the first coil spring part 2A. The metal fitting 30 has a central plate 31, the first side plate 32 and the second side plate 33 and substantially U-shaped form. The nut body 3 into which the coil spring body 2 is stored is fixed to the first side plate 32 by welding and the like.SELECTED DRAWING: Figure 1 |
