る。The bolt of the present invention is formed by press working, and the side plate portion 2 is formed at a right angle around the insertion hole 4 in the central portion, which will be described below with reference to the accompanying drawings. The seat plate 1 is provided by bending and has a notch 3 on the tip side of the side plate portion 2, and a hexagon bolt 5 of mass production type. Insert the hexagon bolt 5 into the insertion hole 4 of the seat plate 1 with the threaded portion 6
To the base end portion of the shaft portion 7, the side plate portion 2 is tightened, the seat plate 1 is fixed to the enlarged head portion 8 of the hexagon bolt 5 to form the head portion 9, and the notch 3 of the seat plate 1 is rotated. The concave portion 10 for use.
