As is apparent from the above description, according to the first aspect of the present invention, since the hub and the disk are separate bodies, the disk is not restrained by the hub even if the disk expands or contracts due to frictional heat. There is an effect that thermal distortion does not occur. Further, since two or more air guide plates and a large number of heat transfer plates are provided in the ventilation path, the heat radiation area is large, and in the pin hole, two friction plates and at least two air guide plates are provided. Therefore, the heat transfer area between the pin and the pin is large, and both have an effect of helping to cool the disk portion.
