PROBLEM TO BE SOLVED: To provide an impact absorption structure of a vehicle body capable of more efficiently absorbing impact energy.SOLUTION: An impact absorption box 12 is arranged between a vehicle body front side end part and a bumper reinforcement 13 of a front side member 10 and a lower member 11. The impact absorption box 12 is provided with: a pipe-shaped upper side impact absorption part 14 and a lower side impact absorption part 15 extending in a vehicle body longitudinal direction by forming a closed cross section; and a pipe-shaped front side connection part 16 for connecting those vehicle body front side end parts and extending in a vehicle body vertical direction by forming a closed cross section. A part more on a vehicle rear side from the connection part 16 in a part between the upper side impact absorption part 14 and the lower side impact absorption part 15, is formed as a communication part 18 for communicating the impact absorption box 12 in a vehicle body width direction.

    【課題】より効率的に衝撃エネルギーを吸収することのできる車体の衝撃吸収構造を提供する。【解決手段】フロントサイドメンバー10およびロアメンバー11の車体前側の端部とバンパーリーンフォースメント13との間に、衝撃吸収ボックス12を配置する。そして、その衝撃吸収ボックス12に、閉断面をなして車体前後方向に延びる管形状の上側衝撃吸収部14および下側衝撃吸収部15と、それらの車体前側の端部とを連結する、閉断面をなして車体上下方向に延びる管形状の前側連結部16とを設けるとともに、上側衝撃吸収部14と下側衝撃吸収部15の間の部分における、前側連結部16よりも車体後側の部分を、衝撃吸収ボックス12を車体幅方向に連通する連通部18とした。【選択図】図1
