Abstract
Disclosed is an automobile underbody structure, wherein a pair of laterally-spaced floor framesare disposed to extend longitudinally in such a manner as to interpose a tunnel regionof a front floor portiontherebetween and joined to a bottom surface of the front floor portion, and a cross memberis disposed to extend laterally so as to connect each side-silland the tunnel regionand joined to a top surface of the front floor portion. Each of the floor framesis gradually inclined laterally inward toward the rear end thereof so as to be obliquely disposed relative to the cross memberin top plan view. A rearward displacement of the floor framesduring a head-on collision exerts a compressive force on a region of the cross memberlocated on the laterally outward side relative to each of the floor frames, and a tensile force on a region of the cross memberlocated on the laterally inward side relative to each of the floor frames. 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.
