電機の冷却装置。[Scope of Claim for Utility Model Registration] 1. A part of the boss member for mounting a rotary shaft is inserted into a through hole opened in the bottom wall of a yoke formed approximately in the shape of a bowl, and a part of the boss member is formed on the outer periphery of the boss member. The flange and the bottom wall of the yoke are fixed via rivets, and a rotor consisting of a plurality of magnets arranged around the inner circumference of the yoke rotates around a generator housed in the yoke. In the cooling device for a magnet generator, a plurality of ventilation holes are provided in the bottom wall of the yoke around the through hole, and a plurality of projections are provided on the boss member mounting surface side of the yoke bottom wall between each ventilation hole. A cooling device for a magnet generator, characterized in that a step portion is formed on a yoke mounting surface of the flange so as to close a gap between the protrusions on an inner peripheral side thereof. 2 In place of the protrusions protruding from the boss member attachment surface of the yoke bottom wall, insertion holes are provided between each ventilation hole in the yoke bottom wall, and the magnetic case is inserted into these insertion holes. 2. The cooling device for a magnet generator as claimed in claim 1, wherein the positioning projection is inserted through the yoke bottom wall and projected toward the boss member mounting surface of the yoke bottom wall. 3 Instead of the protrusion protruding from the boss member mounting surface of the yoke bottom wall, a circular ring-shaped base,
A fan consisting of a plurality of wing parts protruding from this base is mounted between the yoke bottom wall and the flange of the boss member with each wing part facing the boss member mounting surface of the yoke bottom wall. The wing section is provided corresponding to each ventilation hole, and its cross-sectional shape is such that the outer circumference side of the base is open, and a part of the inner circumference side of the base of each wing section is formed in a shape that can be inserted into each ventilation hole. A cooling device for a magnet generator as set forth in claim 1 of the utility model registration claim, characterized in that:
