PROBLEM TO BE SOLVED: To provide a crash box capable of maintaining a stable joint state irrespective of the direction of a shock load.SOLUTION: A crash box 10 is formed by joining flange parts 34A and 36A of an upper member 16 and a lower member 18 to flange parts 34B and 36B, respectively. The flange part 34A is provided with a joint surface 46A constituted by a first flat surface 48A extending in the vehicle width direction and a second flat surface 50A inclined inward and downward in the vehicle width direction from an inner end portion of the first flat surface 48A in the vehicle width direction. Therefore, when a shock load is applied to the crash box 10 from the direction perpendicular to the first flat surface 48A, only a delamination load component fv is applied between the first flat surface 48A and adhesive A. At this time, a load component (shear load component fh) in parallel to the second flat surface 50A is applied between the second flat surface 50A and the adhesive A, so that a joint strength between the joint surfaces 46A and 46B improves.SELECTED DRAWING: Figure 4

    【課題】衝撃荷重の方向に拘らず、安定した接合状態を維持できるクラッシュボックスを提供する【解決手段】クラッシュボックス10は、上部材16と下部材18のフランジ部34A、36Aとフランジ部34B、36Bとを接合することにより形成されている。フランジ部34Aは、車両幅方向に延在する第1平面48Aと第1平面48Aの車両幅方向内側端部から車両幅方向内側下方へ傾斜した第2平面50Aとからなる接合面46Aを備える。したがって、第1平面48Aに垂直な方向から衝撃荷重がクラッシュボックス10に作用すると、第1平面48Aと接着剤Aの間には剥離荷重成分fvのみが作用する。この際、第2平面50Aと接着剤Aの間には、第2平面50Aに平行な荷重成分(剪断荷重成分fh)が作用するため、接合面46A、46Bの接合強度が向上する。【選択図】図4
