The electromagnetic coil 5 is wound to the teeth 3 via insulators 4 so as to surround the extending direction of the teeth 3. The teeth 3 and the insulators 4 constitute a coil winding core 6 of the electromagnetic coil 5, and the side face 6a (4a) of the electromagnetic coil winding part 6 (the insulators 4) that faces the axial-direction winding part 5a of the electromagnetic coil 5 is formed into a protruded face salient at the center in the motor rotation axial direction so that the electromagnetic coil winding part 6 (the insulators 4) and the axial-direction winding part 5a that extends in the motor rotation axial direction of the electromagnetic coil 5 contact with each other without creating the clearance therebetween.
