To provide a shock absorption member that can be used for a bumper and the like of a vehicle, has excellent strength and shock absorption property, can achieve those properties at high yield, has reduced weight and is environmentally friendly.SOLUTION: A shock absorption member is formed by welding and joining a first hollow member 11 to a second hollow member 12 which are made of an aluminum alloy. The shock absorption member is formed so that a weld material and a weld bead W do not project from joint surfaces of the first hollow member 11 and the second hollow member 12.SELECTED DRAWING: Figure 2
【課題】自動車のバンパー等として使用可能な、強度及び衝撃吸収性に優れ、これらの特性を高い歩留りで達成することが可能な、重量を軽減し、環境問題に配慮した衝撃吸収部材を提供する。【解決手段】アルミニウム合金製の第1中空部材11及び第2中空部材12が、互いに溶接接合してなる衝撃吸収部材であって、前記第1中空部材11及び前記第2中空部材12の接合面から、溶接材及び溶接ビードWが突出していないようにして衝撃吸収部材を形成する。【選択図】図2
