To provide a disc wheel for vehicle which comprises a wheel disc for vehicle having a high rigidity.SOLUTION: A wheel disc for vehicle, which is fitted to a hub of an axle, is provided with plural bolt holes for insertion of plural bolts. The wheel disc for vehicle comprises a fitting part which is fitted to the hub in such a manner that the fitting is tightened by the plural bolts and plural nuts. The fitting part has a flat plate part, plural nut support parts, and plural pressing parts which are concaved inward in the vehicle width direction with respect to the flat plate part. When the fitting part is equally divided into the same number of reference areas as the plural nut support parts in a circumferential direction so that the nut support part is positioned at each center viewed from an axial direction, the pressing part is provided on the same number of reference areas respectively. The pressing part has a circular or a circular arc-shaped inner edge provided along an outer edge of the nut support part viewed from the axial direction.SELECTED DRAWING: Figure 2

    【課題】高剛性の車両用ホイールディスクを備えた車両用ディスクホイールを提供する。【解決手段】車軸のハブに取り付けられる車両用ホイールディスクには、複数のボルトを通すための複数のボルト孔が形成されている。当該車両用ホイールディスクは、前記複数のボルトと前記複数のナットとによって締め付けられることによって前記ハブに取り付けられる取り付け部を備える。前記取り付け部は、平板部と、複数のナット支持部と、前記平板部に対して車幅方向内側に凹む複数の押し付け部とを有する。軸方向から見て、それぞれの中心に前記ナット支持部が位置するように、前記取り付け部を周方向に前記複数のナット支持部と同数の基準領域に等分割した場合に、前記同数の基準領域それぞれに前記押し付け部が設けられる。軸方向から見て、前記押し付け部は、前記ナット支持部の外縁に沿って設けられた円形状または円弧形状の内縁を有する。【選択図】図2
