The outer peripheral surface (3) includes a cylindrical surface (11); a tapered surface (13) interposed between the cylindrical surface (11) and one annular end face (12) in an axial direction X and formed by roll forming; a smooth circular arc surface (14) interposed between the tapered surface (13) and the cylindrical surface (11); and a smooth circular arc surface (15) interposed between the tapered surface (13) and the end face (12).
