In this state, the head 2 of the bolt 1 is placed on the upper end of the flange 8, and the constricted portion 5 of the bolt 1 and the clinch portion 11 of the die 9 do not have the same height. Then, from this state, the head portion 2 of the bolt 1 is pressed with a predetermined pressing pressure F by a pressing machine or the like.

金属プレート６とが得られる。Then, as shown in FIG. 3, the head 2 of the bolt 1 descends so as to be in close contact with the metal plate 6, and the flange 8 of the metal plate 6 is crushed by the head 2 of the descending bolt 1. . Then, the crushed and plastically deformed flange 8 is pushed into the inside of the constricted portion 5 and the clinch portion 11 whose upper and lower positions match with each other when the bolt 1 is lowered, and the thick portion 12 corresponding to the integrated shape of the both. Is formed. Finally, the bolt 1 and the metal plate 6 are removed from the die 9 to obtain the bolt 1 and the metal plate 6 firmly fixed to each other.

Has a larger thickness T than the plate thickness t of the metal plate 6, and the thick portion 12 is fixed to the shaft portion 3 of the bolt 1 in a large area, so that sufficient fixing strength can be obtained. In particular, the thick part 12
Since the bolt 1 is in the constricted portion 5 of the shaft portion 3 of the bolt 1, the bolt 1 is reliably prevented from coming off, and the thickness T of the thick portion 12 is equal to that of the metal plate 6 as described above. Since it is larger than the plate thickness t, the bolt 1 can be surely prevented from falling down, and the rotation preventing function of the bolt can be improved by increasing the contact surface.

A cylindrical clinch portion 13 having a flat bottom surface is formed. Therefore, a thick portion 14 having a shape corresponding to the clinch portion 13 is formed on the peripheral portion of the fixing hole 7 of the metal plate 6. Since the thick portion 14 has a larger capacity than the thick portion 12 of the previous embodiment, the strength of the thick portion 14 itself is high and the fixing strength of the bolt 1 to the shaft portion 3 is high. still,
Since the thick portion 14 has a large capacity, the flange for forming the thick portion 14 is formed longer than that in the previous embodiment.

Since the clinch portion 15 has a large capacity as in the second embodiment, the clinch portion 15 has high fixing strength to the shaft portion 3 of the bolt 1. Further, since the bottom surface of the clinch portion 15 is curved, the crushed flange is slippery in the clinch portion 11, the plastic deformation in the clinch portion 15 is smooth, and the clinched portion 15 is crushed. Is filled without any gap, and a dense thick portion 16 having a solid structure is formed.

This 4th Embodiment shows the example which reversed the direction of the flange 8 of the metal plate 6 of 1st Embodiment. Thus, even if the direction of the flange 8 is reversed, the flange 8 can be crushed to form the thick portion 12 (see FIG. 4). However, since the metal plate 6 does not adhere to the surface of the die 9 and the metal plate 6 becomes unstable, another means for holding the metal plate 6 is required.
