The hollow-shaped material 60 constituting the end portion of the underframe 10 in the width direction is provided with a hollow-shaped material 65 corresponding to a part of a side sill. A hollow-shaped material 90 at the lower end of a side structure 20 is provided with a hollow-shaped material 95 corresponding to a part of a side sill. An overlap between a projecting segment 101 of the side sill 95 and the upper surface of the side sill 65 is welded from above.
