収される。At this time, the tip of the stud bolt 7 comes into pressure contact with the bottom of the locating hole 8, and the outer surface 4a of the molding 4 comes into pressure contact with the mold surface 12a. Since the outer surface 4a of the molding 4 is smoothly continuous with the mold surface 1211, the molding 4
Even if the positional accuracy varies due to deformation such as warpage, a gap will not be formed between the mold surface 12a and the molding outer surface 4a, and the occurrence of flaws will be prevented. Also,
If the twi degree varies by mall 4 as above,
The positional error of the stud bolt 7 is absorbed by the deflection of the elastic body 9.
