Claims

[Scope of utility model registration request]

(1) In a rotor of a magnet generator in which a plurality of magnets are arranged at intervals on the inner periphery of a bowl-shaped yoke, a plurality of magnet storage chambers having shapes corresponding to the magnets are arranged in an upper open frame. A case is fitted into the yoke, which is formed by connecting the yoke in an annular manner, and has a groove extending in the height direction on the inner circumferential surface of each partition wall between adjacent storage chambers. The magnet is fitted into each storage chamber with a pole piece arranged on the inner surface, and the groove is contracted and closed by each pole piece to elastically deform the partition part, and the reaction force of this deformation causes the magnet to be inserted through the pole piece. A rotor for a magnet generator, characterized in that the rotor is fixed by being attached to the inner circumferential surface of the yoke.

(2) The magnet according to claim 1, wherein the partition wall is supported in an upright state by press-fitting a rib of a presser ring aligned on the case into the groove. generator rotor.
