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 inserted into the yoke, and the height of each partition wall between adjacent storage chambers is set lower than the height of the magnet. A pole piece whose height is set to be lower than the height of the magnet is placed on the inner surface of the magnet, and the magnet is fitted into the magnet.Furthermore, a retainer ring is brought into contact with the top surface of the case, and the mouth edge of the yoke is turned inward. A rotor for a magnet generator, characterized in that the magnet is clamped and fixed between a holding ring and a floor wall of a storage chamber.

(2) A claim for utility model registration characterized in that the case has a protrusion on the lower surface of the center of the storage floor wall, and this protrusion is fitted into a closure hole drilled in the bottom wall of the yoke. A rotor for a magnet generator according to scope 1.

(3) A rotor for a magnet generator according to claim 2, wherein the protrusion is larger than the stopper hole.

(4) A rotor for a magnet generator according to claim 2 or 3, wherein the protrusion has an annular groove recessed at its base.
