Vehicle Body

Abstract: ABSTRACT “VEHICLE BODY” In a floor cross member (4) that has a groove-type cross-sectional shape, which has a web surface (4a) that is an upper surface, a ridge portion (4b) continuous from the web surface (4a), and a vertical wall surface (4c) continuous from the ridge portion (4b), and a tensile strength of at least 440MPa, a flange (4e) is formed around both end portions in the longitudinal direction in such a manner as to be continuous from the web surface (4a), the ridge portion (4b), and the vertical wall surface (4c), and the floor cross member (4) is bonded to a tunnel portion (2a) and a side sill (3) via the flange (4e). The flange width lfc at the center of the circumferential direction of a curved portion (4e-2) of the flange (4e) is equal to or larger than the minimum flange width lfs of the curved portion (4e-2). Therefore, provided is a vehicle body that prevents the deformation of the floor cross member (4) and improves the torsional rigidity.
