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 yoke, and a cylindrical cover is fitted inside the magnet, an upper flange is attached to the top of the cover. It is formed to protrude outward in the radial direction, and
A lower flange is formed at the bottom of the cover so as to protrude inward in the radial direction, and a plurality of notches are opened in the upper flange along the radial direction to reduce the gap between the adjacent magnets. A plurality of bent portions slightly larger than the magnet are formed, and by bending each bent portion, each bent portion is fitted into the gap on the top side of the adjacent magnet, and furthermore, the lower flange portion is fitted into the yoke bottom. A rotor of a magnetic generator characterized by being fixed to a wall.
