PROBLEM TO BE SOLVED: To incorporate permanent magnets for power generation into a core and prevent the exposed portions of the permanent magnets from becoming rusted, while preventing magnetic short-circuiting in the permanent magnets. SOLUTION: The core 4 with a power generation coil 8 as an exciter coil for ignition wound on it is placed at a position opposite to the circumferential surface of a rotor 1 typified by a flywheel. The permanent magnets 10 are inserted into cut holes, formed in the magnetic poles 5 and 7 of the core 4. At least one inductor 11, that forms the magnetic path of magnetic flux produced by the permanent magnets 10, is provided on the circumferential surface of the rotor 1. A resin cover 20 is attached that includes a magnet cover that covers the exposed portions of the permanent magnets 10, and a coil case that houses the exciter coil 8. The exciter coil 8 attached to the core 4 and the permanent magnets 10 are sealed with resin, in a process in which the resin cover 20 is molded. COPYRIGHT: (C)2006,JPO&NCIPI
