Abstract

A car body for railway rolling stock wherein a plurality of outside plates forming the car body are joined to frame members of the car body by spot welding. The outside plates are produced of a ferrous material except for stainless steel and a film or coating is provided on an outside surface of the outside plates. By virtue of the joining of the outside plates to the frame members and the joining of the outside plates to each other by spot welding, less input heat is required as compared with a continuous welding; therefore, outside plate distortion can be reduced and time and labor for manufacturing of the car body can be reduced. Moreover, since the outside plates are produced of a ferrous material, the painting of the outside surfaces of the outside plates can easily be accomplished.

Claims

1. A car body for railway rolling stock including two end constructions, two side constructions, a roof construction and an underframe, said side constructions comprising a plurality of outside plates and a plurality of frame members joined to each other, said plurality of outside plates being made of a ferrous material and sized to fit on an outer surface of said framing, two of said plurality of said outside plates being disposed adjacent to each other, a joggled section formed in one end of one of said two outside plates so as to enable adjacent ends of said two outside plates to be disposed in an overlapping condition, said jogged section having a depth corresponding to a thickness of the other of said two outside plates, said frame members include two outside plate joining surfaces, one of said joining surfaces being located inwardly of the car body and the other joining surface being located outwardly of said car body by a distance corresponding to the depth of said joggled section, the adjacent ends of said outside plates in the overlapped condition being fitted into one of said outside plate joining surfaces, wherein said plurality of outside plates are joined to said framing by spot welding at a periphery thereof and at the adjacent ends of the outside plates in the overlapped condition, and wherein a coating is provided on an outer surface of each of said outside plates.
