To stabilize a collision energy absorption amount in an impact absorber for a door.SOLUTION: An impact absorber for a door includes: a top plate 33 to which an impact load is input from a vehicle side surface during a side collision; plate members 35 extending from the top plate 33 toward a door trim 10; first reinforcement ribs 36 erected on one surface of each plate member 35; and second reinforcement ribs 38 erected on the other surface. A height of the first reinforcement rib 36 is lower than a height of the second reinforcement rib 38. A length of the first reinforcement rib 36 which extends from the top plate 33 toward the door trim 10 is shorter than a length of the second reinforcement rib 38 which extends from the top plate 33 toward the door trim 10.SELECTED DRAWING: Figure 4
【課題】ドア用衝撃吸収体において衝突エネルギーの吸収量を安定させる。【解決手段】側突の際に車両側面からの衝撃荷重が入力される天板33と、天板33からドアトリム10に向かって延びる複数の板部材35と、板部材35の一方の面に立設する第1補強リブ36と、他方の面に立設する第2補強リブ38と、を含み、第1補強リブ36の高さが第2補強リブ38の高さよりも低く、第1補強リブ36の天板33からドアトリム10に向かって延びる長さが第2補強リブ38の天板33からドアトリム10に向かって延びる長さよりも短い。【選択図】図4
