PROBLEM TO BE SOLVED: To provide a vehicle body front structure of an automobile which can suppress the drop of vehicle body deceleration during a vehicle collision without causing problems such as increases in the number of components and the vehicle body weight.SOLUTION: A vehicle body front structure of an automobile comprises left and right side members 7, and left and right front pillar parts 3b. Both end parts 20'' of a front cross member 20 extending in a vehicle width direction are joined to the left and right front pillar parts 3b. The front cross member 20 is curved so that a vehicle width direction center part 20' protrudes to the vehicle front from both end parts 20''. The front end position of the center part 20' of the front cross member 20 and the position of a front end surface 7a of the side member 7 are matched approximately in a vehicle longitudinal direction.
【課題】部品点数及び車体重量が増えるといった問題を招くことなく、車両衝突時の車体減速度の落ち込みを抑制できる自動車の車体前部構造を提供する。【解決手段】左,右のサイドメンバ7と左,右のフロントピラー部3bとを備えた自動車の車体前部構造であって、左,右のフロントピラー3bに車幅方向に延びるフロントクロスメンバ20の両端部20′′を結合し、該フロントクロスメンバ20を、車幅方向中央部20′が両端部20′′より車両前方に迫り出すように湾曲形成し、フロントクロスメンバ20の中央部20′の前端位置と、サイドメンバ7の前端面7a位置とを車両前後方向に略一致させた。【選択図】図3
