PROBLEM TO BE SOLVED: To obtain a vehicle skeleton structure which can efficiently transmit a collision load at a front face collision to a locker side.SOLUTION: A metal-made dash cross member 40 is continuously connected to a lower end side of a fiber-reinforced resin-made dash panel 38, and the dash cross member 40 comprises a closed cross section structure extending to a vehicle width direction. The front side member 60 is fixed to the dash cross member 40 in a state of abutting thereon, and a rear-face side lower part being a region at the outside of the dash cross member 40 in the vehicle width direction is fixed to a locker 22 in a state of abutting thereon. In a metal-made pillar lower outer 32, a main body part 34 is joined to the locker 22, and a front-side extension part 36 extending from the main body part 34 to the inside of a vehicle front oblique direction in the vehicle width direction is joined to a side face part 60S at the outside of the front side member 60 in the vehicle width direction.SELECTED DRAWING: Figure 1
【課題】前面衝突時の衝突荷重をロッカ側に効率的に伝達させることができる車両骨格構造を得る。【解決手段】繊維強化樹脂製のダッシュパネル38の下端側に金属製のダッシュクロスメンバ40が連接されており、ダッシュクロスメンバ40は、車両幅方向に延在する閉断面構造を備えている。フロントサイドメンバ60は、ダッシュクロスメンバ40に突き当てられた状態で固定され、ダッシュクロスメンバ40の車両幅方向外側の部位でかつ後面側下部は、ロッカ22に突き当てられた状態で固定されている。また、金属製のピラーロアアウタ32は、その本体部34がロッカ22に接合されると共に、本体部34から車両前方斜め車両幅方向内側に延出された前側延出部36がフロントサイドメンバ60の車両幅方向外側の側面部60Sに接合されている。【選択図】図1
