高度な技術が必要とされていた。However, according to the fastening structure shown in FIG. 5, since the mounting portion AT of the other sheet metal A has to be bent at a right angle, the work is very troublesome. The squareness of both sheet metal A and B is the other sheet metal A
Since it is determined by the bending accuracy of bending the mounting portion AT of at a right angle, even a slight deviation in this bending accuracy causes a deviation in the squareness, making it impossible to mount both sheet metals A and B at a right angle. Therefore, the installation required fairly advanced technology.

が難しい等の問題があった。Further, since the other sheet metal A has the mounting portion AT bent at a right angle fastened to the upper surface of the one sheet metal B by the screw C, the plate thickness of the mounting portion AT and the screw C are fixed as shown in FIG. Since the head of the above will project on the one sheet metal B by the dimension D, the appearance is not good and the right-angled state cannot be taken out properly. Furthermore, the dimension D affects the sheet metal on the other sheet metal A. There is a problem that it is difficult to accurately determine the dimensions of the mounting hole and the other sheet metal B.

Then, if a tapping screw is screwed from the bottom side of one sheet metal into the notch formed in the other sheet metal, the plastic deformation due to the screwing exerts the caulking effect, so that the other sheet metal is placed on the upper surface of one sheet metal. Since it can be fastened at a right angle, and it is not necessary to bend the mounting portion at a right angle for mounting, it is possible to mount both sheet metals easily and at an accurate right angle, and at the same time, bend them. Since it is not affected by the plate thickness and the like, the mounting portion can be mounted in a right-angled state with a good appearance and also with high dimensional accuracy.

If a tapping screw is screwed in between the insert protrusions, it can be attached at a right angle to the other plate, but when the insert protrusion is inserted, the stepped portions formed on the left and right sides of the insert protrusion are on one plate. In order to prevent the other sheet metal from swinging to the left and right by contacting the upper surfaces of both edges of the fitting hole formed in, the other sheet metal is placed in a right angle state in cooperation with the plastic deformation due to the screwing of the tapping screw. Enables secure fastening.
