As described in claim 2, the guide pin arranged on the inner diameter of the coil can be applied to a coil having a small outer diameter portion. As described in claim 3, the guide pin provided upright on the outer diameter portion of the coil is suitable for application to a coil having an extremely small inner diameter. As described in claim 4, there is no fear of impairing the strength of the rotor by making the guide pin thick enough to make the resin side non-penetrating. According to a fifth aspect of the present invention, the printed wiring thin plate is provided with a communicating portion extending from the inner diameter to the outer diameter of the air-core coil, and the resin is made to flow into the inner diameter of the air-core coil during molding. Since it is resin-molded with, the electromagnetic vibration of the air-core coil can be prevented and the weight of the rotor itself is increased.
