Hinge structure of bonnet of motor car

If the colliding body strike the upper portion of the hood and the hood hinge portion opposite the front, pass from the hood to hood hinge load value greater than or equal to a set value, the front hood hinge arm to the portion of the hood there is a travel under. A longitudinal wall portion of the substrate (22) in a vehicle lateral inwardly deformed around the flex point, the hood of the vehicle with respect to lateral deformation. Compared to a fixed hood itself with respect to the vehicle in a longitudinal or vertical direction relative to the hood that is less likely to occur in the case where the deformation direction of the deformation, the amount of deformation of the hood is increased, the peak load acting on the colliding body Save small.
