ABSTRACT:
The manufacturing method of a rotor holder according to the present invention includes a step in which a top plate portion having a substantially discoid shape substantially centered about a central axis, and a side wall portion extending from an outer circumferential edge of the top plate portion are formed simultaneously by feeding a metal plate in a predetermined direction and pressing the metal plate by a die. Also, the present manufacturing method includes a step in which a punched portion is formed at the side wall portion.
