Zusammenfassung:PURPOSE: A hub for coupling a fan with a motor shaft is provided to insert a riveting protrusion integrated with the circumferential surface of the hub into a fan and perform a plurality of riveting works by one time punching work using a press, thereby shortening work time. CONSTITUTION: A riveting protrusion of a hub(30) penetrates a riveting hole of a fan(20) and the end of the riveting protrusion is inserted into the riveting hole. The riveting protrusion integrated with the circumferential surface of one side of the hub is radially formed. A motor shaft(12) is inserted into the center of the circumferential surface of the other side of the hub. The hub is fixed to a shaft connection boss so that the hub is not separated from the motor shaft by screw coupling.
