Abstract
【解決手段】衝突判定システム10を備えたフロントバンパ12では、バンパカバー30の対向壁部36が、チャンバ部材20の前面20Aと対向して配置されている。この対向壁部36には突出部42が一体に形成されており、突出部42は対向壁部36からチャンバ部材20側(車両後側)へ突出されている。すなわち、フロントバンパ12では、バンパカバー30とチャンバ部材20との間にアブソーバ28が介在されておらず、バンパカバー30とチャンバ部材20との間の隙間G2が突出部42によって詰められて、突出部42がチャンバ部材20の前面20Aを押圧する構造とされている。これにより、チャンバ部材20よりも温度変化しにくいバンパカバー30によって隙間G2が詰められているため、フロントバンパ12を温度による影響を受けにくい構造にできる。
