The flange portion comprises a plurality of main extended portions in which a plurality of fastening holes are formed to penetrate in an axial direction while being arranged to be spaced apart from each other along a circumferential direction so that a wheel is mounted to the flange portion. The plurality of main extended portions are formed to extend along a plurality of virtual extension reference lines which extend in the radially outward direction.
