Abstract:
A portion of a steel plate (11) constituting a material for a core is a deformed steel plate (24) having protruding pieces (23) formed by bending portions of a bottom (12), the protruding pieces (23) being able to protrude towards an inner circumference side of a yoke, the protruding pieces (23) having holes (25) formed therethrough. It is thereby possible to include, in the deformed steel plate (24), a portion of scrap formed by punching the steel plate (11) using a press as the protruding pieces (23), and thus, it is possible to reduce the amount of scrap.
