The present invention provides a vehicle support structure and a method for manufacturing the vehicle support structure, the vehicle support structure being provided with a machining reference hole, the machining reference hole allowing a positioning jig to be inserted during machining to reliably support a cast body, and preventing water from accumulating in a state in which the vehicle support structure is mounted on a vehicle. The suspension arm manufactured by casting has a machining reference hole (7) formed during casting. The machining reference hole (7) is formed to be longer in the direction of the bend generated in the molding step of the suspension arm. A recess (8) is formed on the suspension arm, one end of the recess (8) is communicated with the machining reference hole (7), and the other end of the recess (8) is opened outwards.
本发明提供如下这样的车辆用支承构造体和车辆用支承构造体的制造方法,该车辆用支承构造体具备加工基准孔,该加工基准孔能够在机械加工时供定位用的治具插入而可靠地支承铸造体,并且防止在搭载于车辆的状态下积存水。由铸造制造的悬挂臂具有在铸造时形成的加工基准孔(7)。加工基准孔(7)在悬挂臂的在成型工序中产生的弯曲的方向上形成得较长。该悬挂臂形成有凹部(8),该凹部(8)的一端与加工基准孔(7)连通并且另一端向外方开放。
