PROBLEM TO BE SOLVED: To provide a bumper reinforcement structure that is configured so as to increase loads to be transmitted to a crash can at an initial stage of a small overlap collision, and increase loads to be absorbed by being crushed and deformed at a later stage of the small overlap collision.SOLUTION: The bumper reinforcement structure is provided with a bumper reinforcement panel 25 covering a front surface of a bumper reinforcement main body 21 and is provided with a swelling-out part 26 which is a closed cross section structure and extends from a site which overlaps with at least a part outside in a vehicle width direction of a front surface of a crash can 12 in the bumper reinforcement panel 25, to outside in the vehicle width direction more than the crash can 12 to swell out toward a tip of the vehicle. Bending rigidity in the vehicle longitudinal direction of the bumper reinforcement main body 21 and the swelling-put part 26 is higher than bearing force in the longitudinal direction of the crash can 12.SELECTED DRAWING: Figure 6
【課題】スモールオーバラップ衝突の初期にクラッシュカンへの荷重伝達量を増加させると共に、スモールオーバラップ衝突の後期には潰れ変形により荷重吸収量の増加を図るバンパレインフォースメント構造を提供する。【解決手段】バンパレインフォースメント本体21の正面を覆うバンパレインフォースメントパネル25が設けられ、バンパレインフォースメントパネル25におけるクラッシュカン12正面の少なくとも車幅方向外側の一部と重複する部位からクラッシュカン12よりも車幅方向外側まで延び、かつ車両先端方向に膨出する閉断面構造の膨出部26が設けられると共に、バンパレインフォースメント本体21および膨出部26の車両前後方向の曲げ剛性は、クラッシュカン12の前後方向の耐力よりも高剛性とされたことを特徴とする。【選択図】図6
