To provide a support structure for a vehicle and manufacturing method of the support structure for the vehicle which is provided with a working standard hole which can support a casting surely by inserting a jig for positioning during machining and at the same time prevents water from being accumulated in such a condition as to install on the vehicle.SOLUTION: A suspension arm manufactured by casting includes a working standard hole 7 which is formed at casting. The working standard hole 7 is formed long in a curve direction of the suspension arm which generates in molding process. There is formed a concave part 8 which allows one end to pass through the working standard hole 7 and at the same time allows other end to open to outside.SELECTED DRAWING: Figure 5

    【課題】機械加工時に、位置決め用の治具を挿入して鋳造体を確実に支持することができるとともに、車両に搭載した状態で、水が溜まることを防止した加工基準穴を備えた車両用支持構造体及び車両用支持構造体の製造方法を提供する。【解決手段】鋳造により製造されるサスペンションアームは鋳造時に形成される加工基準穴7を有する。加工基準穴7は成型工程において発生するサスペンションアームの曲がり方向に長く形成される。加工基準穴7に一端を通じさせるとともに他端を外方に開放させた凹部8を形成する。【選択図】図5
