To provide an undercover which can make compatible both the protection of a vehicle from a road face, and the protection of a pedestrian from a vehicle front face collision.SOLUTION: An undercover 10 has a protrusive shape part 13 which is protrusively curved or bent to a side opposite to a vehicle 100, and a rib 20 is arranged at a cover outside face 10b of the undercover 10 while extending to a vehicle longitudinal direction. Therefore, at a road face input, compression force acts on the cover outside face 10b of the undercover 10, and the rib 20 is compressed. On the other hand, at a collision with a pedestrian, tensile force acts on the cover outside face 10b of the undercover 10, and the rib 20 is tensed. Here, a fragile part 21 is arranged at a part of the rib 20 in an extension direction. By this constitution, at the collision with the pedestrian, the rib 20 starts to be cracked with the fragile part 21 as a starting point, thus lowering rigidity, and a load necessary for the deformation (breakage) of the undercover 10 can be thereby set small at the collision with the pedestrian compared with the case of the road face input.SELECTED DRAWING: Figure 3

    【課題】路面からの車両保護と車両前面衝突による歩行者保護を両立できるアンダーカバーの提供。【解決手段】アンダーカバー10が車両100と反対側に凸状に湾曲または屈曲する凸形状部13を有しており、アンダーカバー10のカバー外側面10bにリブ20が車両前後方向に延びて設けられている。そのため、路面入力の際にはアンダーカバー10にはカバー外側面10bに圧縮力が働きリブ20は圧縮となる。一方、歩行者衝突時にはアンダーカバー10にはカバー外側面10bに引っ張り力が働きリブ20は引っ張りとなる。ここで、リブ20の延び方向の一部に脆弱部21が設けられている。そのため、歩行者衝突時には脆弱部21を起点にしてリブ20が裂けていき強度が低下するため、路面入力の際に比べて、歩行者衝突時のほうがアンダーカバー10の変形(破損)に要する荷重を低く設定できる。【選択図】 図3
