PROBLEM TO BE SOLVED: To provide a bumper reinforcement structure in which reinforcement plates are used for a body member to obtain predetermined flexural strength, but which can suppress weight increase as much as possible.SOLUTION: A bumper reinforcement structure 10 to be provided at a front or rear portion of a motor vehicle body includes: an elongated body member 14 having a hitting surface that receives the load upon a vehicle impact; and support structures for the motor vehicle body to receive the load applied on the body member 14. The body member 14 has a hat-shaped vertical section of which the rear side is opened. At least within the lateral range between the support structures, of the body member 14, strip reinforcement plates 20A, 20B formed separately from each other are disposed being spaced apart from each other, and fixed at upper and lower end portions respectively, of the opening of the hat-shaped vertical section.SELECTED DRAWING: Figure 4

    【課題】バンパリインフォースメント構造の本体部材に補強板を用いて所定の曲げ耐力を得る場合でも、重量増加を極力抑制することにある。【解決手段】バンパリインフォースメント構造10は、自動車車体の前部または後部に配設され、車両衝突時に荷重を受ける当たり面を有する長尺形状の本体部材14と、該本体部材14に作用する荷重を自動車車体で受けるための支持構造とを備える。そして、前記本体部材14は縦断面形状の後方が開口したハット型断面形状とされており、前記本体部材14の少なくとも支持構造間の幅方向範囲内には前記ハット型断面の開口する上下端部にそれぞれ固定される長尺板形状の各補強板20A,20Bを別部材として形成し離間して配置している。【選択図】図4
