The invention provides a vehicle front portion structure which improves an impact absorption structure of a vehicle front portion with respect to collision loads from above. A cowl louver (30) is disposed below a cowl upper cover plate (22), which is an outer plate member on the upper surface of a front vehicle body. The cowl louver (30) has a vertical wall (40) provided upright from the cowl panel (34) in the direction of the expected load (F). The vertical wall (40) bends at one location between the upper edge (40a) and the lower edge (40b), and the length (upper width (a)) from the ridge line (40c) at the bending position to the upper edge (40a) is different from the length (lower width (b)) from the ridge line (40c) at the bending position to the lower edge (40b). During deformation of the vertical wall (40) caused by a collision, energy is continuously consumed so that an impact is absorbed by moving the bent portion on the vertical wall (40).
本发明提供一种对车辆前部对于来自上方的碰撞载荷的冲击吸收结构进行改善的车辆前部结构。在作为前部车身的上表面的外板部件的前围上盖板(22)的下方处,对前围百叶板(30)进行配置。前围百叶板(30)具有朝向所设想的载荷(F)的方向而从前围板(34)起被直立设置的纵壁(40)。纵壁(40)在上边缘(40a)与下边缘(40b)之间的一个部位处发生屈曲,从屈曲位置的棱线(40c)起至上边缘(40a)为止的长度(上侧宽度(a))、和从屈曲位置的棱线(40c)起至下边缘(40b)为止的长度(下侧宽度(b))不相同。在由碰撞所引起的纵壁(40)的变形过程中,通过使屈曲部在纵壁(40)上进行移动,从而持续性地消耗能量,以使冲击被吸收。
