形成する。Next, the caulking portion 18 is formed by using the caulking tool 3.
To form As the caulking tool 3, a tool having an insertion projection 31 at the tip and having a pressing surface 32 continuous with its peripheral surface is used. Then, the insertion protrusion 31 of the caulking tool 3 is press-fitted into the recess 16 of the head 11, and the pressing surface 32 forms the thick portion 1.
7 is deformed so as to be bent outward, thereby forming a caulked portion 18.
