According to a body structure of the present invention, a floor panel member is reinforced by a pair of first members, and the second member comprised of plural pipes is disposed along the width of a vehicle so as to integrate the first members 1. An end of the second member is extended along the longitudinal side of the vehicle and is fixed by welding in the state of penetrating into a side sill. There is no necessity of providing any reinforcement material because the second member has a high strength continuously along the width of the vehicle. Moreover, there is no necessity of increasing a board thickness for the purpose of securing the rigidity because the second member penetrates into the side sill. On the other hand, the second member can be manufactured by cutting an existing steel pipe to a predetermined side, and it is therefore possible to cope with the change in the width of the vehicle only by changing a cutting size.
