To increase the amount of energy absorption by surely generating deformation by a fragile part.SOLUTION: A vehicle body front part structure includes: a front side frame 1 extending in a vehicle front-back direction and including at least two ridge lines 1c, 1d; a stiffener 16 overlapped with the two ridge lines 1c, 1d along a longitudinal direction; and a bulk head 17 overlapped with the stiffener 16. The stiffener 16 is disposed to extend in the vehicle front-back direction while straddling the bulk head 17. A fragile part 20 is formed at the front side frame 1 to be located near the bulk head 17.SELECTED DRAWING: Figure 2

    【課題】脆弱部によって変形を確実に生じさせて衝撃エネルギ吸収量を増大させる。【解決手段】車両の前後方向に延設され、少なくとも二つの稜線1c,1dを有するフロントサイドフレーム1と、二つの稜線1c,1dに重ねられて長手方向に沿うスチフナ16と、スチフナ16に重ねられるバルクヘッド17と、を備えている。スチフナ16は、バルクヘッド17を跨いで車両前後方向へ延設され、フロントサイドフレーム1には、バルクヘッド17の近傍に脆弱部20が形成されている。【選択図】図2
