Claims

[Scope of utility model registration request]

A cooling device for a magnet generator, in which a rotor consisting of a plurality of magnets arranged around the inner periphery of a yoke formed in a roughly bowl shape rotates around a generator housed in the yoke. A plurality of through holes are arranged in the circumferential direction from the bottom wall to the side wall of the yoke and are opened to communicate between the inside and outside of the yoke, and the radially inner portion of the through hole is fixed to the yoke. The outer surface of the yoke bottom wall is covered by the flange portion of the boss member, and each through hole has a duct integrally formed with the magnet case, and the radially inner and outer surfaces of the through hole are covered with a duct formed integrally with the magnet case. 1. A cooling device for a magnet generator, characterized in that each of the magnet generators is formed to have an opening, and each of the magnet generators is fitted.
