To provide a cowl grille structure for a vehicle that is able to secure a sufficient stroke for absorbing impact energy by, even if the rigidity of a material is reduced, transmitting a load to a corner portion and causing folded deformation with the corner portion as a fulcrum.SOLUTION: A cowl grille 30 includes: an upper wall portion 31a extending in a vehicle width direction and a vehicle longitudinal direction; and front and rear vertical wall portions 31d, 31e extending downward from a front end and a rear end of the upper wall portion 31a via corner portions 31b, 31c. The upper wall portion 31a includes: a load input portion 31F to which a downward load is inputted from a bonnet 18 in the event of a collision; a front side portion 31g on a vehicle front side from the load input portion 31F; and a rear side portion 31h on a vehicle rear side from the load input portion 31F. Each of the front side portion 31g and the rear side portion 31h is formed in a straight line in a vehicle side-view, and the load input portion 31F is formed so as to project upward toward the bonnet 18 side.SELECTED DRAWING: Figure 6
【課題】材料の剛性を下げても角部に荷重を伝達して、当該角部を支点とする折り畳み変形により衝撃エネルギ吸収用の充分なストロークを確保する車両のカウルグリル構造を提供する。【解決手段】カウルグリル30は、車幅方向、車両前後方向に延びる上壁部31aと、上壁部31aの前端、後端から角部31b,31cを介して下方に延びる前側、後側の縦壁部31d,31eと、を備え、上壁部31aは、衝突時にボンネット18から下向き荷重が入力される荷重入力部31Fと、荷重入力部31Fよりも車両前方側の前辺部31gと、荷重入力部31Fよりも車両後方側の後辺部31hと、を備え、前辺部31gと後辺部31hとは、車両側面視で各々直線状に形成され、荷重入力部31Fはボンネット18側に向けて上方へ突出するように形成されたことを特徴とする。【選択図】図6
