A vehicle body structure comprise a cross member and a floor. Two parallel side members extend along a longitudinal central line of a vehicle and outwardly from the cross member. The cross member is formed by extrusion in a first direction lying in parallel to a transverse line crossing the longitudinal central line. The floor is formed by extrusion in a second direction lying in parallel to the longitudinal central line. The floor includes a recess recessed inwardly and a floor panel portion that defines at least a portion of the recess defining edge. The cross member has an integral tooth fitted into the recess and connected to said floor along the recess defining edge.
