To improve bending strength of a closed cross section structure in a longitudinal direction to inhibit deformation of a vehicle body reinforcement structure caused when the vehicle body reinforcement structure receives an impact load while inhibiting increase of the weight in the vehicle body reinforcement structure including the closed cross section structure, such as a center pillar, which is located at a portion that receives the impact load and formed in an elongated shape.SOLUTION: A reinforcement plate 14 includes a first bending part 14a and a second bending part 14b. The first bending part 14a and the second bending part 14b are bent so that one of them protrudes to the front surface side of the reinforcement plate 14 and the other protrudes to the rear surface side of the reinforcement plate 14. In the reinforcement plate 14, a first side part 14c is sandwiched at a joint part 10a. A second side part 14d is disposed along a first side part 13e of an extending part 13 of an inner reinforcement 12. Further, a third side part 14e is disposed along a second side part 13f of the extending part 13 to be joined thereto.SELECTED DRAWING: Figure 2

    【課題】センタピラーのように、衝突荷重を受ける部位にあって長尺に形成された閉断面構造体を含む車体補強構造において、閉断面構造体の長手方向での折れ曲がり強度を高めることにより、重量増加を抑制しつつ、衝突荷重を受けた際の車体補強構造の変形を抑制する。【解決手段】補強プレート14は、第1屈曲部14aに並べて第2屈曲部14bを備える。第1屈曲部14a及び第2屈曲部14bは、その一方が補強プレート14の表面側に凸となるように屈曲され、他方が補強プレート14の裏面側に凸となるように屈曲されている。補強プレート14において、第1辺部14cは、接合部10aにおいて挟持されている。第2辺部14dはインナリインフォースメント12の拡大部13の第1辺部13eに沿って配置されている。また、第3辺部14eは、拡大部13の第2辺部13fに沿って配置されて接合されている。【選択図】図2
