Abstract: Provide an electromagnetic switch device for a starter, by which a winding fluctuation of a plurality of coils, of which wire diameters are different from each other, is prevented, which can be downsized and can be produced with a low cost. A bobbin, at which winding portions are separated by using a first flange portion which includes a first notch portion, second notch portions, and third notch portions, by which coils are led out, and a first separation wall and a second separation wall, which include the second notch portions and the third notch portions, by which coils are led out, is included, and a main aspiration holding coil, a sub-aspiration holding coil, and a resistance coil, of which wire diameters are different from each other, which are respectively wound around a first winding portion, a second winding portion, and a third winding portion, which are separated, are provided.

Abstract: This rotating electric machine rotor has a rotor coil composed of; a lower coil field wound around the outer circumference of a winding drum portion of a bobbin; and a mountain-wound coil field wound around the outer circumference of the lower coil field. A cross point in the mountain-wound coil field and a cross point in the lower coil field are shifted from each other in the circumferential direction. Thus, it becomes possible to shift the cross point positions without changing the thickness of the winding drum portion of the bobbin and without using a tape or the like.
