The outer side of the inclined part 24 is brought into contact with the pressing surface 62p, and from this state, the member is further pressed to deform the inclined part 24 outward in the radial direction, and the member is then pulled out from the mold 5 to allow the material constituting the inclined part 24 moved outward in the radial direction beyond the first diameter to be ironed by the first inner peripheral surface 61s.
