To provide a wheel disk for a vehicle with high rigidity, and a disk wheel for a vehicle including the same.SOLUTION: A mounting part 18 of a disk 14 has a flat plate part 24 with a pressed surface that is pressed against a hub of an axle, and a plurality of nut support parts 26 that protrude in an axial direction of the disk 14 from the flat plate part 24 toward the opposite side of the pressed surface, and each of which has a ring shape when viewed from the axial direction. A bolt hole 28 is formed so as to penetrate the nut support part 26 in the axial direction. The nut support part 26 has extending parts 26b that curve so as to expand toward outside a radial direction of the nut support part 26, and projecting parts 26c that are adjacent to the extending parts 26b in a circumferential direction of the nut support part 26 and that protrude toward inside the radial direction of the nut support part 26 with respect to the extending parts 26b.SELECTED DRAWING: Figure 4

    【課題】高剛性の車両用ホイールディスクおよびそれを備えた車両用ディスクホイールを提供する。【解決手段】ディスク14の取り付け部18は、車軸のハブに押し付けられる押し付け面を有する平板部24と、ディスク14の軸方向において平板部24から前記押し付け面とは反対側に向かって突出しかつ前記軸方向から見て円環形状を有する複数のナット支持部26とを有する。ナット支持部26を前記軸方向に貫通するようにボルト孔28形成されている。ナット支持部26は、ナット支持部26の径方向外側に向かって膨らむように湾曲する張出部26bと、ナット支持部26の周方向において張出部26bに隣り合いかつ張出部26bに対してナット支持部26の径方向内側に向かって突出する突出部26cとを有する。【選択図】図4
