Abstract

First (30a) and second (30b) inclined faces of an inclined face (30) extending radially inward and rearward from a rocking edge (29) formed so as to coincide with a front edge of a saddle face (28) of a body part of a metal element (23) are molded by press forming a metal element material using a mold (47). An inclined face-corresponding part (30') of the metal element material (23), which corresponds to the inclined face of the metal element, includes a first inclined face-corresponding portion (30a') inclined rearward at a first inclination angle from a rocking edge-corresponding part (29') , and a second inclined face-corresponding portion (30b') inclined rearward at a second inclination angle, which is larger than the first inclination angle, from a radially inner end of the first inclined face-corresponding portion (30a'). The mold (47) includes a first inclined face-molding portion (47c) inclined rearward at the first inclination angle from a rocking edge-molding portion (47b) abutting against the rocking edge-corresponding part (29').
