PROBLEM TO BE SOLVED: To provide a vehicular front structure which can absorb prescribed collision energy.SOLUTION: A vehicular front structure comprises: a pair of side members which are provided on both sides of a vehicle body; a pair crash boxes which comprise a cylindrical member provided at a front end part of each of the pair of side members, and are collapsed by energy equal to or more than a prescribed value from a vehicle body front side; a bumper beam which is constructed on the pair of crash boxes at respective front ends of the pair of crash boxes; a nut member of which one end is fixed to the bumper beam in the state of penetrating a through hole provided on the bumper beam in a front area of the crash box, and with which a traction bolt is engaged; and a bowl-type holding member of which a cross section is gradually reduced an opening of the crash box toward the nut member, and which is joined to the bumper beam and is joined to the other end of the nut member. The side member has an opening, which permits retraction of the nut member and the holding member when collapsing the crash box, on a front face thereof.SELECTED DRAWING: Figure 4

    【課題】所定の衝突エネルギーを吸収できる車両の前部構造を提供する。【解決手段】車両の前部構造は、車体両側に設けられる一対のサイドメンバと、一対のサイドメンバのそれぞれの前端部に設けられる筒状の部材であって、車体前側からの所定以上のエネルギーで圧潰する一対のクラッシュボックスと、一対のクラッシュボックスのそれぞれの前端部において一対のクラッシュボックスに架設されるバンパービームと、クラッシュボックスの前方域において、バンパービームに設けられた貫通穴に貫通した状態でバンパービームに一端部が固定され、牽引ボルトが螺合するナット部材と、クラッシュボックスの開口からナット部材に向けて横断面が漸次縮小する碗型であって、バンパービームに接合されるとともに、ナット部材の他端部に接合される保持部材と、を備え、サイドメンバは、その前面に、クラッシュボックスの圧潰時にナット部材及び保持部材の後退を許容する開口を有する。【選択図】 図4
