Claims

[Scope of utility model registration request]

(1) In a rotor of a magnet generator having a boss provided as a member for connecting to an engine, a flywheel made of a bowl-shaped magnetic material attached to the boss, and a magnet provided on the inner periphery of the flywheel, A cylindrical ring made of a thin plate metal is provided on the inner circumferential surface of the magnet, and the magnet is housed between the outer circumferential surface of this ring and the inner circumferential surface of the flywheel, and the magnet is located at the open end of the flywheel. One end of the ring is bent toward the outer circumferential side, and between the inner circumferential surface of the ring and the inner circumferential surface of the flywheel, the bent part of the ring, the magnet, and a part of the end of the flywheel bottom side of the ring are A rotor of a magnet generator, which is filled with a non-magnetic material so as to surround it.

(2) Make the ring into a shape with a part cut off, bend the cut part toward the outer circumference, insert it into the gap between the magnets, and fill the bent part with a non-magnetic material up to the inner circumference. A rotor for a magnet generator according to claim 1 of the utility model registration claim.
