Abstract
The present invention provides a magnet generator that can reduce a mass without lowering a desired inertia and can prevent an engine from being locked by vibration or impact in a high rotation speed region. In a magnet generator including a rotor including a bowl-like flywheel having a cylindrical section and a ceiling section, a plurality of permanent magnets arranged over the inner circumferential wall surface of the cylindrical section, and a boss arranged in the center of the ceiling section and attached to an output shaft of an engine, and a stator facing the permanent magnets, fixed to the engine side inside the flywheel and including laminated steel plates and coils, wherein at least a part of the ceiling section of the flywheel is formed of a synthetic resin and the remaining part is formed of a metal.
