ラアン。The rotor includes a stator and a rotor that are arranged to face each other, and the rotor has a shaft that is rotatably supported on the stator side, a rotor yoke and a blade support that rotate integrally with the shaft, and a rotor that faces the stator. In the branless DC fan including a magnet supported by the rotor yoke and a rotary blade supported by the blade support, a rotation preventing portion and a slipping prevention portion made of a combination of concave and convex portions are formed in a part of the shaft. , a rotation prevention portion consisting of a combination of concave and convex portions is formed on an inner peripheral surface of either or both of the rotor yoke or the blade support body adjacent to the rotation prevention portion and the retaining portion of the shaft, and the rotation prevention portion is formed on the shaft. In the brushless straight line, the rotation prevention part and the fall prevention part and the rotation prevention part formed on one or both of the rotor yoke or the blade support are covered with Guicast metal and fixed to each other. ``Ryu Raan.
