To provide a vehicular wheel, which is configured so that air resistance caused by arranging a protruding part can be reduced.SOLUTION: A spoke 40 has a spoke-circumferential intermediate part 41 and spoke-circumferential end parts 42 positioned at end parts near opening parts 50 at both sides in a wheel circumferential direction of the spoke-circumferential intermediate part and comprising protruding parts 43 protruding to outside in a wheel shaft direction. The protruding parts 43 have opening part side surfaces 43a, surfaces near the opening parts 50 and spoke center side surfaces 43b, whose angles formed with the wheel shaft direction are larger than angles formed by the opening part side surfaces 43a and the direction, which lead at a tilt angle to an outer side surface 41a in the wheel shaft direction of the spoke-circumferential intermediate part 41. In the protruding parts 43, sides thereof closer to outside in a wheel radial direction become wider in wheel circumferential width and become lower in height in the wheel shaft direction, and in the spoke center side surfaces 43b of the protruding parts 43, the angles formed with the wheel shaft direction become larger toward outside in the wheel radial direction.SELECTED DRAWING: Figure 3
【課題】突出部を設けることによる空気抵抗を低減できる、車両用ホイールの提供。【解決手段】 スポーク40が、スポーク周方向中間部41と、スポーク周方向中間部のホイール周方向両側で開口部50側の端部にあり、ホイール軸方向外側に突出する突出部43を備えるスポーク周方向端部42と、を有する。突出部43は、開口部50側の面である開口部側面43aと、開口部側面43aよりもホイール軸方向とのなす角が大とされておりスポーク周方向中間部41のホイール軸方向外側面41aに傾斜した角度で連なるスポーク中央側面43bと、を有する。突出部43は、ホイール半径方向外側ほど、ホイール周方向幅が広くなるとともにホイール軸方向高さが低くなっており、突出部43のスポーク中央側面43bは、ホイール軸方向とのなす角がホイール半径方向外側ほど大となっている。【選択図】 図3
