To provide a vehicle knuckle made of aluminum alloy which improves rigidity against a force from outside to inside in a vehicle width direction.SOLUTION: A high mount knuckle 11 includes a bearing support part 111, a knuckle upper part 113, and a knuckle lower part 112. In an attitude such that the high mount knuckle 11 is mounted on a vehicle body, and the knuckle upper part 113 has a shape such that the knuckle upper part 113 is equally divided into 5 or more regions in a vertical direction, the center of the bearing support part 111 is fixed, and when a horizontal load F from outside toward inside in a vehicle width direction is applied to a knuckle upper end 115, the minimum value of a value dividing by a mass in each region corresponding to strain energy in each of other regions excluding a first region 11A out of the 5 or more regions becomes 0.70 or more the maximum value.SELECTED DRAWING: Figure 2

    【課題】アルミニウム合金製の車両用ナックルにおける、車両幅方向外側から内側に向かう力に対する剛性を向上する。【解決手段】ハイマウントナックル11は、軸受支持部111と、ナックル上部113と、ナックル下部112と、を備える。ハイマウントナックル11が車両本体に装着された姿勢において、ナックル上部113を鉛直方向に沿って5つ以上の領域に等分分割し、軸受支持部111の中心が固定されるとともにナックル上端部115に車両幅方向外側から内側に向かう水平荷重Fを加えた場合の、前記5つ以上の領域のうちの第1領域11Aを除く他の領域のそれぞれにおけるひずみエネルギを対応する各領域の質量で除した値の最小値が最大値の0.70以上となる形状をナックル上部113が有している。【選択図】図2
