To provide a vehicle support structure in which a weak part provided in a molded product can be destroyed by a collision load in the event of a vehicle collision.SOLUTION: A vehicle support structure 1 is a molded product having a healthy part made of an alloy, and is configured such that the hardness continuously increases from a weak part 4 (or weak part 5) formed by heating a local area to the healthy part, wherein the hardness of the healthy part is greater than HRB45, and the hardness of the weak part is HRB45 or less.SELECTED DRAWING: Figure 1
【課題】鋳造品に設けた脆弱部が車両衝突時の衝突荷重によって破壊可能な車両用支持構造体を提供することを目的とする。【解決手段】車両用支持構造体1は、合金からなる健全部を有する鋳造品であって、局部を加熱して形成した脆弱部4(または脆弱部5)から連続して硬度が大きくなって前記健全部になっている構成であり、前記健全部の硬度はHRB45より大きい状態であり、前記脆弱部の硬度はHRB45以下の状態である。【選択図】図1
