る。The flywheel opening side end is the outer flange portion 5a of the magnet cover 5.
The magnet 4 is wrapped around the entire circumference with a flywheel member 1d so as to be pressed in the axial direction of the flywheel. In this case, an adhesive is interposed between the inner peripheral surface and end surface of the magnet, the outer periphery of the cylindrical portion of the magnet cover, and the magnet abutting portion of the outer flange. In this way, the flywheel is magnetized so that a predetermined number of N and poles are lined up in the circumferential direction.
