As shown in FIG. 4, when the inclined surface 11b is bent with respect to the reference surface 11a, the boss 12 and the boss insertion hole 13 are formed.
Are not formed in the same direction, the ultrasonic crimping cannot be performed simultaneously from the same direction to form the tip of the boss 12 on the retaining head 17, and the crimping operation becomes complicated,
This hinders automation of caulking work by a robot or the like. Therefore, as shown in FIG. 5, an attempt was made to form the boss 12 and the boss insertion hole 13 in the same direction, but at the inclined surface 11b, a gap S was formed between the retaining head 17 and the molding base material 11. Are formed, the crimping force becomes unstable, and a screw cannot be used as the retaining head 17.
