Abstract

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 L 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 L 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.
