37 and the winding end 39, a flat surface 41 passing through the center of the temporary core portion 45.
Since the pressing force is applied to the temporary core portion 45 in the vertical direction with respect to the plane 41 in the upper position to manufacture the elliptical core portion 35, the winding start end 37 of the core portion 35 is It is located at the end of the central straight part of the part 35, and also the winding end end 39 of the core part
Is located almost at the center of the outer peripheral curved portion.
この結果、第１図に示したように、コア部35の中央に
従来形成されていた空間部はなくなり、また、コア部35
