Car body of a railway car

摘要

A railway car body is produced with high accuracy in an easy manner. An underframe 10 is formed by joining together a plurality of hollow members 50,60 that extend in the longitudinal direction of the car body. The hollow member 60 constituting the end portion of the underframe 10 in the width direction is provided with a hollow portion 65 corresponding to a part of a side sill. The hollow member 90 at the lower end of a side structure 20 is provided with a hollow portion 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. An overlap between a projecting segment 103 of the lower end and a projecting segment 73 is welded from below. The size of the overlap is selected in accordance with the shrinkage of the underframe 10 when welding the bolsters thereto. <IMAGE>
