To provide a bumper reinforcement that restrains reduction in strength against collision load while enabling ventilation of the bumper reinforcement by reinforcing the bumper reinforcement with a pipe capable of ventilation.SOLUTION: Openings 11a, 12a are respectively arranged in a hat cross-section member 11 and a plate-like member 12 so as to enable ventilation in a collision load direction in a closed cross-section structure 10a. A pipe 13 communicating between the respective openings 11a, 12a of the hat cross-section member 11 and the plate-like member 12 in the closed cross-section structure 10a is provided between the hat cross-section member 11 and the plate-like member 12. The pipe 13 is made of fiber-reinforced plastic, and fiber of the fiber reinforced plastic is oriented along the collision load direction.SELECTED DRAWING: Figure 1

    【課題】バンパリインフォースメントにおいて、通風可能なパイプによりバンパリインフォースメントを補強することにより、バンパリインフォースメントの通風を可能としながら衝突荷重に対する強度低下を抑制する。【解決手段】ハット断面部材11及び板状部材12には、閉断面構造体10a内を衝突荷重方向に通風可能とするように開口11a、12aがそれぞれ設けられており、ハット断面部材11及び板状部材12の間には、閉断面構造体10a内でハット断面部材11及び板状部材12の各開口11a、12a間を連通させるパイプ13を備え、パイプ13は、繊維強化プラスチック製であり、繊維強化プラスチックの繊維が衝突荷重方向に沿って配向されている。【選択図】図1
