PURPOSE:To obtain a metal fixture which lessens the number of parts and reduces assembling processes and further, which can be economically produced. CONSTITUTION:A metal fixture is constituted of a cylindrical nut 12 provided with a collar 14 which can be fitted in such a way that it is inserted in the dovetail groove A and turned almost 90 degree and a restrictive member 13 preventing the rotation of the cylindrical nut 12. The restrictive member 13 of the rotation is provided with a stopper plate 16 having a stopper piece 15 inserted into the dovetail groove A to restrict the rotation, a spring 17 engaging the stopper plate 16 toward the collar 14 and a fitting part 18 mutually fitted with the cylindrical nut 12, and these are integrated. A groove 19 is provided at the lower part of the cylindrical nut 12 and a protrusion 21 is provided at the inside face of a fitting hole 20 made at the fitting part 18 of the restrictive member 13 of the rotation. The cylindrical nut 12 and the restrictive number 13 of the rotation are connected by fitting the protrusion 21 to the groove 19. |
