Claims

[Scope of utility model registration request]

In a rotor of a magnet generator in which a plurality of magnets are arranged at intervals around the inner circumference of a cylindrical yoke, there is provided a top open frame with a plurality of magnet storage chambers having substantially the same shape as the magnets and an open top. A case formed by connecting the magnets in an annular manner is fitted into the yoke, and the magnet is fitted into each housing chamber of the case with a pole piece made of a thin plate arranged on the inner surface, and the upper part of the case is opened. The same number of convex portions protruding from the lower surface of the presser ring are respectively fitted into the concave portions formed on the upper surface of the frame, and the pole piece is pressed with a part of the upper open frame to elastically deform it. A rotor for a magnet generator, characterized in that the magnet is inserted into and fixed to the inner peripheral surface of the yoke by force.
