ABSTRACT:
Disclosed is an automobile underbody structure, wherein a pair of laterally-spaced floor frames10are disposed to extend longitudinally in such a manner as to interpose a tunnel region6of a front floor portion2therebetween and joined to a bottom surface of the front floor portion2, and a cross member15, 16is disposed to extend laterally so as to connect each side-sill7and the tunnel region6and joined to a top surface of the front floor portion2. Each of the floor frames10is gradually inclined laterally inward toward the rear end thereof so as to be obliquely disposed relative to the cross member15, 16in top plan view. A rearward displacement of the floor frames10during a head-on collision exerts a compressive force on a region of the cross member15, 16located on the laterally outward side relative to each of the floor frames10, and a tensile force on a region of the cross member15, 16located on the laterally inward side relative to each of the floor frames10. The automobile underbody structure of the present invention makes it possible to effectively receive a shock during a head-on collision by the cross member.
