PROBLEM TO BE SOLVED: To enhance a collision energy absorption effect of a front frame provided on a front part of a floor panel.SOLUTION: A front frame structure of a vehicle comprises: a main frame 21 fixed to a front part of a floor panel of a vehicle; an inclination frame 15 extended from a bent part 13 on a front end of the main frame 21 to a front side and outward of a vehicle width direction; and a V-shaped frame 22 formed of an inside frame 17 and an outside frame 18 which are expanded in a V-shape to inside and outside of a vehicle width direction, to a rear side from a front apex 16. The inside frame 17 is connected to the main frame 21 on a rear side of the bent part 13, the outside frame 18 is connected to the inclination frame 15 on a front side of the bent part 13, and an outer end in a vehicle width direction of a bumper beam 24 is supported to the apex 16 of the V-shaped frame 22 through a bumper beam extension 23. During small overlap collision time, the inclination frame 15 is folded outward of the vehicle width direction, from the bent part 13 on a front end of the main frame 21, for efficiently absorbing collision energy.SELECTED DRAWING: Figure 8

    【課題】フロアパネルの前部に設けられた前部フレームの衝突エネルギー吸収効果を高める。【解決手段】自動車のフロアパネルの前部に固定されたメインフレーム21と、メインフレーム21の前端の屈曲部13から前方かつ車幅方向外側に延びる傾斜フレーム15と、前方の頂部16から後方に向かって車幅方向内外にV字状に拡開する内側フレーム17および外側フレーム18よりなるV字状フレーム22とを備え、内側フレーム17は屈曲部13の後方のメインフレーム21に接続されるとともに外側フレーム18は屈曲部13の前方の傾斜フレーム15に接続され、V字状フレーム22の頂部16にバンパービームエクステンション23を介してバンパービーム24の車幅方向外端が支持され、スモールオーバーラップ衝突時に傾斜フレーム15がメインフレーム21の前端の屈曲部13から車幅方向外側に折れ曲がることで、衝突エネルギーを効果的に吸収することができる。【選択図】図8
