Zusammenfassung:To improve an impact absorption structure of a vehicle front part against an impact load from above.SOLUTION: A cowl louver 30 is disposed below a cowl top 22 that is an outer plate member on the upper surface of a front part vehicle body. The cowl louver 30 includes a vertical wall 40 disposed vertically from a cowl panel 34 toward the direction of an expected load F. The vertical wall 40 is bent at one location between an upper edge 40a and a lower edge 40b, and a length (an upper width a) from a ridge line 40c on the bent position to the upper edge 40a and a length (a lower width b) from the ridge line to the lower edge 40b are different. In a deformation process of the vertical wall 40 due to a collision, the bent portion moves on the vertical wall 40, and thus energy is persistently consumed, and impact is absorbed.SELECTED DRAWING: Figure 3 【課題】上方からの衝突荷重に対する車両前部の衝撃吸収構造を改善する。【解決手段】前部車体の上面の外板部材であるカウルトップ22の下方に、カウルルーバー30を配置する。カウルルーバー30は、想定される荷重Fの方向に向けてカウルパネル34から立設された縦壁40を有する。縦壁40は、上縁40aと下縁40bの間の1箇所で屈曲しており、屈曲位置の稜線40cから上縁40aまでの長さ(上側幅a)と、下縁40bまでの長さ(下側幅b)が異なる。衝突による縦壁40の変形過程で、屈曲部が縦壁40上を移動することで、持続的にエネルギが消費され、衝撃が吸収される。【選択図】図3
