[0031] First, the vehicle front structure 10 related to the first embodiment will be described. Such as figure 1 with figure 2 As shown, a pair of front side members 14 extending in the longitudinal direction of the vehicle body are provided on the front side of the vehicle 12 so as to be separated from each other to the left and right sides at predetermined intervals. Such as figure 1 with image 3 As shown, since the inner plate 14A of the hat-shaped cross section and the outer plate 14B of the flat plate shape are joined together, each of the front side members 14 is formed into a rectangular closed cross-sectional shape.

[0032] Such as figure 1 with figure 2 As shown, a crash box 16 having a rectangular closed cross-sectional shape is provided at the front end of each of the front side members 14. In detail, a rectangular frame-shaped flange portion 14C is integrally formed at the front end portion of the front side member 14. A flange portion 16A having a rectangular fr...

Abstract

A vehicle front portion structure including: front side members disposed along a vehicle body longitudinal direction, whose vehicle body front portion sides are disposed at a higher position than vehicle body rear portion sides thereof; a sub-frame that is disposed at a vehicle body lower side of the front side members at the vehicle body front portion sides of the front side members, due to front side fixed portions of the sub-frame being mounted to the vehicle body front portion sides of the front side members, and rear side fixed portions of the sub-frame being mounted to the vehicle body rear portion sides of the front side members; mount supporting portions provided at midway portions in the vehicle body longitudinal direction of the sub-frame, to which engine mounts are mounted; and connecting members that connect the mount supporting portions with the front side members.

Description

Technical field [0001] The invention relates to a vehicle front structure. Background technique [0002] There is generally a known structure as follows (for example, see Japanese Patent Application (JP-A) Publication Nos. 2008-174179 and 2005-047363): in the structure, a vehicle front structure with a subframe There is a connecting member, wherein the sub-frame is supported by the engine on the underside of the vehicle body of the front side member. When viewed from the lateral side of the vehicle, the connecting member connects the longitudinal middle part of the sub-frame and the front Side member. [0003] At the subframe, the vibration in the vertical direction of the vehicle body is excited by engine vibration. However, in the structure described above, the connecting member is not connected to the region where the amount of deformation (amplitude) of the sub-frame is the largest, and therefore, the vibration of the sub-frame in the vertical direction of the vehicle body ca...
