Abstract

A support frame is provided to extend upward and rearward from a portion of a front side frame near a suspension tower substantially straight and connect to an upper portion of a hinge pillar. Accordingly, there can be provided a front structure of an automotive vehicle that can properly restrain a forward deformation of a cabin by transmitting an impact load at a vehicle frontal crash to the hinge pillar efficiently.

Description

technical field [0001] The present invention relates to a front body structure of an automobile provided with a hinge strut, a dash panel, a suspension support tower and a front side member. Background technique [0002] Conventionally, as a front body structure of an automobile as described above, for example, there is a structure disclosed in Japanese Patent Application Laid-Open No. 2003-182633. [0003] That is, if Figure 18 Shown, this structure comprises, left and right hinge struts 91,91 ( Figure 18 Only the structure on the right side of the vehicle is shown in the figure); it is joined with the above-mentioned two left and right hinge pillars 91, 91 to separate the engine compartment 92 and the vehicle compartment 93 behind it; A suspension support tower 94 at a certain distance in front of the vehicle; a front side member 95 extending from the front of the vehicle body to the rear and connected to the suspension support tower 94, and the rear end is bent downward...
