To provide a vehicle frame structure which enables reduction of a length of a cabin frame entering an occupant space even if a buffer load is applied from ahead.SOLUTION: A front cabin frame 10 includes: a pair of left and right lower side members 50 extending in a vehicle front-back direction; a pair of left and right first front vertical members 11 extending upward from positions near front ends of the respective lower side members 50; a first front lateral member 13 which extends in a vehicle width direction and connects upper ends of the first front vertical members 11; and connection members 60 each of which connects the first front vertical member 11 with a front side frame 20. In a state that a plane PF including the front side frame 20 is arranged in substantially parallel to a plane PM including the lower side member 50, a rear end of the front side frame 20 is connected to a substantially center part as seen in a vertical direction of the frist front vertical member 11 through the connection member 60.SELECTED DRAWING: Figure 1
【課題】前方から衝突荷重が加えられても乗員空間へのキャビンフレームの侵入量を低減させることができる車両のフレーム構造を提供する。【解決手段】前方キャビンフレーム10は、車両前後方向に延在する左右一対の下方サイドメンバ50と、各下方サイドメンバ50の前端付近から上方に延在する左右一対の第一の前方縦メンバ11と、車両幅方向に延在して第一の前方縦メンバ11の上端同士を連結する第一の前方横メンバ13と、第一の前方縦メンバ11と前方サイドフレーム20とを連結する連結メンバ60と、を有する。前方サイドフレーム20を含む平面PFを、下方サイドメンバ50を含む平面PMと略平行に配置した状態で、連結メンバ60を介して前方サイドフレーム20の後端を第一の前方縦メンバ11の上下方向略中央部に連結する。【選択図】図1
