<p>The present invention minimizes arched deformation of the back surface of a yoke section (3) that occurs when a winding (20) is wound around a tooth section (4) of a core piece (2) that is configured by stacking layers of a magnetic plate material. The yoke section (3) of the core piece (2) that applies the winding (20) is supported from both sides of the stacking direction by an upper pin holder (5a) that is arranged on one side in the stacking direction of the core piece (2) and a lower pin holder (5b) that is arranged on the other side. Each of the pin holders (5a), (5b) that support the core piece (2) is pulled in the opposite direction of the protruding direction of the tooth section (4) of the core piece (2), the entire back surface of the yoke section (3) is pressed against an engagement surface (61a) that faces the back surface (3) of the yoke section (3) of the core piece (2) in order to secure the core piece (2), and the winding (20) is applied to the tooth section (4).</p> |
