One end face thereof has a groove. When a maximum outer diameter of the one end face of the pin is OD (mm), and a total edge length on the one end of the pin is L (mm), the ratio of L to OD is within a predetermined range. The stud comprises: a columnar body in which a recess is formed at one end face thereof in an axial direction; and the pin which is inserted into the recess, and a part including one end face of the pin is projected from the one end face of the body.
