Description of the Related Art Conventionally, the structure of a railway car, for example, the structure of a passenger car, is generally constructed such that side structures are erected on both sides of an underframe and a roof structure is bridged between upper ends of both side grooves. It has a structure in which a section steel and a thin steel plate are welded and connected.

It is assembled in a substantially lattice shape that is connected laterally with a pillow. In addition, the side structure and the roof structure are formed by stretching an outer plate and a roof plate on a frame connected in a substantially lattice shape, and these underframes,
The side structure and the roof structure form a substantially cylindrical structure. In addition, there is an outer skin stress bearing structure in which various loads acting on the structure, such as an impact load in a vertical direction and a front-rear direction, are shared by structural members of the entire structure, that is, frames and outer plates.

担構造による鉄道車両用構体によると、互いに溶接結合
された骨組及び外板で荷重を分担するように構体が形成
されることから、比較的軽量で剛性強度に優れた構体が
容易に得られる。According to the former structure for a railway vehicle having the outer skin stress-bearing structure, since the structure is formed so that the load is shared by the frame and the outer plate welded to each other, the structure is relatively high. A lightweight structure having excellent rigidity and strength can be easily obtained.

ないものである。However, since an extremely long underframe is combined with a long side structure and a long roof structure is provided, this assembling work is not easy and requires a lot of man-hours. Since the load is distributed and loaded by the frameworks and the outer plates that serve as structural members, the underframe, the side structure, and the roof structure are welded to each other so that sufficient load transmission can be performed therebetween, and the underframe, the side structure, and the roof. It is difficult to change the structure alone or a part of the structure to another shape, it is difficult to change the shape of the structure, and the effect of mass production cannot be obtained, and a sufficient reduction in manufacturing cost cannot be obtained.
