PROBLEM TO BE SOLVED: To provide a shock absorbing structure for a vehicle that can sequentially progress destruction from tip end parts to base end side parts of a pair of left and right side wall parts at a collision of the vehicle and thereby securing stable EA performance.SOLUTION: A shock absorbing structure for a vehicle V has a shock absorbing member 2 made of fiber-reinforced resin comprising: a pair of left and right side wall parts 21 arranged at a front end-side part of a vehicle body; an upper connection wall part 22 connecting upper end parts of the pair of side wall parts 21 to each other; and a lower connection wall part 23 connecting lower end parts of the side wall parts to each other. The pair of side wall parts 21 contain a plurality of first carbon fibers arrayed so as to extend continuously in a longitudinal direction. The upper connection wall part 22 contains a plurality of third and fourth carbon fibers which are arrayed so as to extend continuously in a direction obliquely crossing a longitudinal direction and which cross to each other in a mesh shape.SELECTED DRAWING: Figure 1

    【課題】車両衝突時、左右1対の側壁部の先端部分から基端側部分に亙って逐次破壊を進行させることができ、安定したEA性能を確保することができる車両の衝撃吸収構造を提供する。【解決手段】車体前端側部分に配設された左右1対の側壁部21と、これら1対の側壁部21の上端部同士を連結する上連結壁部22と下端部同士を連結する下連結壁部23とを備えた繊維強化樹脂製衝撃吸収部材2を有する車両Vの衝撃吸収構造において、1対の側壁部21が前後方向に連続して延びるように配列された複数の第1炭素繊維を含み、上連結壁部22が前後方向に斜めに交差する方向に連続して延びるように配列された複数の第3,第4炭素繊維であって互いにメッシュ状に交差する複数の第3,第4炭素繊維を含むように構成されている。【選択図】図1
