回転体。(1) Consisting of a main body and a boss, the boss is provided with fitting parts for the rotating shaft on the inner periphery of both ends in the axial direction, and the fitting parts for the rotating shaft are provided on the outer periphery of the boss at positions close to the main body. An annular slit is provided to promote heat flow between the main body and the boss due to a high temperature difference with the environment to flow to the fitting part of the boss, thereby reducing the temperature difference between the outer periphery of the boss and the fitting part. A rotating body fitted to a rotating shaft, characterized by being small in size to reduce thermal stress and prevent loosening of the fit between the rotating shaft and the rotating shaft.
リットを設け、本体部とボスとの間の熱流の主流がはめ
合い部に流れるようにしたことを特徴とする実用新案登
録請求の範囲第１項記載の回転軸にはめられた回転体。(2) Request for registration of a utility model characterized in that an annular slit is provided in the middle part of the inner peripheral part of the boss in the axial direction so that the main stream of heat flow between the main body part and the boss flows to the fitting part. A rotating body fitted to the rotating shaft according to item 1.
