ABSTRACT:
Disclosed is an underbody structure for an automobile, which comprises a pair of laterally-spaced floor frames10disposed to extend longitudinally in such a manner as to interpose a tunnel region6therebetween and joined to a bottom surface of a front floor portion2. Each of the floor frames10has a rear end located in the vicinity of a rear kick-up portion3extending upward from a rear end of the front floor portion2. The rear kick-up portion3and each rear end region of the floor frames10are connected to one another from the exterior side of the automobile through an end gusset45(47, 48). The end gusset45(47, 48) may be designed to define a closed section in cooperation with the rear kick-up portion3, or to extend laterally outward so as to be connected to a front end region of a rear frame17. The underbody structure of the present invention can prevent or suppress a rearward movement of each rear end of the floor frames during a head-on collision.
