To provide a front bulkhead of a vehicle capable of enhancing protection performance to an on-vehicle part while restraining an increase in vehicle weight.SOLUTION: A front bulkhead has a pair of side members 11, a lower cross member 12 and an inside reinforcement plate 15. The lower cross member 12 has a lower wall 12u for blocking up the lower end of the side member 11 by an end part in the extension direction and a flange part extending upward from the front-rear end parts of the lower wall 12u and joined to front-rear walls of the side member 11. A grounding plate 17 for receiving a load in road surface interference time is joined to an undersurface of the lower wall 12u of the end part in the extension direction of the lower cross member 12. The inside reinforcement plate 15 is joined by triple overlapping at least any one joining part of a joining part of the flange part of the lower cross member 12 and front-rear walls of the side member 11 and a joining part of a lower wall of the lower cross member 12 and the grounding plate 17.SELECTED DRAWING: Figure 3

    【課題】車両重量の増加を抑制しつつ、車載部品に対する保護性能を高めることができる車両のフロントバルクヘッドを提供する。【解決手段】フロントバルクヘッドは、一対のサイドメンバ11と、ロアクロスメンバ12と、内側補強プレート15と、を備える。ロアクロスメンバ12は、延出方向の端部がサイドメンバ11の下端を閉塞する下壁12uと、下壁12uの前後の端部から上方に延びサイドメンバ11の前後の壁に接合されるフランジ部と、を有する。ロアクロスメンバ12の延出方向の端部の下壁12uの下面には、路面干渉時に荷重を受ける接地プレート17が接合されている。内側補強プレート15は、ロアクロスメンバ12のフランジ部とサイドメンバ11の前後の壁との接合部と、ロアクロスメンバ12の下壁と接地プレート17との接合部のうちの、少なくともいずれか一方の接合部に三枚重ねで結合されている。【選択図】図3
