Description
図6には、本実施形態の別例に係る補強部材16Aが例示される。補強部材16Aは、前側壁30と後側壁32の幅W1,W2が等しく形成され、平面視で矩形状となる。例えば前側壁30と後側壁32の幅W1,W2は、クラッシュボックス14の幅W3と等しく形成される。また、補強部材16Aの車両前後方向長さL1は、バンパR/F12の前側壁20の内面から後側壁22の内面までの距離L2と等しいことが好適である。
なお、図1~図7に係る実施形態では、車両前部の側方骨格部材としてFrサイドメンバ10を挙げたが、これに限らない。例えばラダーフレーム型の車両においては、サイドレールが側方骨格部材に対応し、当該サイドレールを含む骨格部材に対して、本実施形態に係る補強部材16、16A,16Bを適用可能である。
