PROBLEM TO BE SOLVED: To prevent excess deformation of a side member to vehicular inside upon offset collision by a projecting part made to contact to a side surface of the side member along with deformation of a bumper member so that the deformation of the bumper member is suppressed and the side member is reinforced due to side member extension.SOLUTION: It comprises a side member 2, a bumper member 3 which is arranged at the vehicular frontmost position in a straight line and whose vehicular rear side is jointed with the side member 2, and a front side member extension 4 attached to a front side part of the side member 2. An extension part 31 is arranged on both ends of the bumper member 3 in vehicular width direction, which project outside and extends in an inclined manner from an inflection point outside in vehicular width direction toward vehicular rear side. A projecting part 5 is arranged inside of the extension part 31 in vehicular width direction, which extends toward the side member 2. A forward part of the projecting part 5 at vehicular inside comprises a plane part 52 facing a side part 2a of the side member 2 at vehicular outside. The plane part 52 and the side member extension 4 are arranged in an overlapping manner in vehicular forth and back direction.SELECTED DRAWING: Figure 2
【課題】オフセット衝突時に、バンパメンバの変形に合わせて突出部をサイドメンバの側面に当接させ、バンパメンバの変形を抑え、サイドメンバエクステンションによりサイドメンバを補強してサイドメンバが車両内側へ変形し過ぎるのを防ぐ。【解決手段】サイドメンバ2と、車両最先端の位置で直線的に配置され、かつ車両後方側がサイドメンバ2に接合されるバンパメンバ3と、サイドメンバ2の先端部に取付けられるフロントサイドメンバエクステンション4とを有し、バンパメンバ3の車両幅方向の両端には、外側に張り出し、車両幅方向外側の屈曲点より車両後方へ向かって傾斜しながら延びる張出部31が設けられ、張出部31の車両幅方向内側には、サイドメンバ2に向かって延びる突出部5が設けられ、突出部5の車両内側の先端部は、サイドメンバ2の車両外側の側面部2aに対向する平面部52を有し、平面部52とサイドメンバエクステンション4とは、車両前後方向で重なるように配置されている。【選択図】図2
