PROBLEM TO BE SOLVED: To provide a steering knuckle for a vehicle which suppresses deformation and breakage of an arm part and increases the degree of weight reduction as compared with a conventional steering knuckle.SOLUTION: A steering knuckle for a vehicle comprises: a body part to which an axle is mounted; an arm part integrally connected to the outer periphery of the body part at one end, and extending outward from the body part along a stretching axis; and a connection part connected to the other end of the arm part, to which a vehicle constituent member is connected. The arm part has a first portion, a second portion, and a hollow part. The first portion has a peripheral wall comprising an opening in which a part thereof opens around the stretching axis. The second portion includes a peripheral wall formed so as to close around the stretching axis. In a cross section crossing the stretching axis, an end part on the opening side of the peripheral wall of the first portion includes a wide part having a thickness thicker than a plurality of side parts adjacent to the end part.SELECTED DRAWING: Figure 1

    【課題】 従来のステアリングナックルと比較して、アーム部の変形および破損がより抑制され、軽量化の程度を高めた車両用ステアリングナックルを提供する。【解決手段】 車軸が装着される本体部と、一端が前記本体部の外周に一体的に接続されているとともに、当該本体部から延伸軸に沿い外方に延びるアーム部と、前記アーム部の他端に接続された、車両構成部材が連結される連結部と、を有する車両用ステアリングナックルを提供する。前記アーム部は、第1部位と、第2部位と、中空部とを有する。前記第1部位は、前記延伸軸周りにおいて一部が開口した開口部を備える周壁を有する。前記第2部位は、前記延伸軸周りにおいて閉じるように形成された周壁を含む。前記延伸軸に交差する断面において、前記第1部位の周壁の前記開口部側の端部は、当該端部と隣接する複数の側部よりも厚さが厚い拡幅部を含む。【選択図】 図1
