Description
図1に示すように、本実施形態のバンパリンフォース10は、車両2の後端部に配置される。バンパリンフォース10は、車両後端に配置されるリアバンパ6の車両内側、即ち、車両前側に配置される。バンパリンフォース10は、車両2の後方からの衝突の際に、荷重を受けて、車両2の変形を抑制する。
図4に示すように、バンパリンフォース210は、突出部14に替えて、突出部214を備える。また、バンパリンフォース210は、突出部216を備える。その他のバンパリンフォース210の構成は、バンパリンフォース10の構成と同様である。
図5に示すように、バンパリンフォース310は、突出部14に替えて、突出部314を備える。その他のバンパリンフォース310の構成は、バンパリンフォース10の構成と同様である。
