Zusammenfassung:PROBLEM TO BE SOLVED: To provide a vehicle front structure in which, folded width of an energy absorption member is wider on a lower side than on an upper side.SOLUTION: A vehicle front structure comprises: a front bumper cross member 4 forming a front bumper extending in a vehicle width direction on a front part of a vehicle; and an energy absorption member 5 fixed to a front face of the front bumper cross member 4 and having a polygonal closed cross sectional shape which is collapsed when the vehicle collides by head-on collision. The energy absorption member 5 comprises: a fixing side plate 51 having a front face plate part 51a arranged along the front face of the front bumper cross member 4, and a rear plate part 51b arranged and extending from the front face plate part to rearward in a lower region of the front bumper cross member 4; and an absorption side plate 52 having an upper side plate part 52d jointed to the front face plate part 51a and extending forward, a lower side plate part 52e jointed to the rear plate part 51b and extending forward, and a pressure reception plate part 52a disposed between a front end of the upper side plate part 52d and a front end of teh lower side plate part 52e in parallel to the front face plate part 51a.SELECTED DRAWING: Figure 3 【課題】エネルギ吸収部材の折れ曲がり幅が上側よりも下側で広くなる車体前部構造を提供する。【解決手段】車両前部において車幅方向に延在するフロントバンパを構成するフロントバンパクロスメンバ4と、フロントバンパクロスメンバ4の前面に固定され、車両が前面衝突した場合に圧潰する多角形閉断面形状を有するエネルギ吸収部材5と、を備え、エネルギ吸収部材5は、フロントバンパクロスメンバ4の前面に沿って配置される前面板部51aと、フロントバンパクロスメンバ4の下方域で前面板部から後方に延びて配置される後方板部51bと、を有する固定側板51と、前面板部51aに接合され、前方に延びる上側板部52dと、後方板部51bに接合され、前方に延びる下側板部52eと、上側板部の前端52dと下側板部52eの前端と間に前面板部51aと平行に配置される受圧板部52aと、を有する吸収側板52と、を含む。【選択図】図3
