った。2. Description of the Related Art In recent years, there has been an increasing demand for speed improvement in railway vehicles, but problems such as an increase in impact on a track, noise, and an increase in driving power cost arise with the increase in speed. Therefore, in order to solve these problems, it is necessary to significantly reduce the weight of the railway vehicle. However, it is also possible to reduce the weight and to secure the strength and rigidity of the vehicle body equal to or higher than the conventional one. Particularly, large pressure fluctuations occur in a short period of time in a vehicle body traveling in a tunnel at a high speed, and it is important to improve the strength of the vehicle body against this pressure load. The pressure load is shared by bone members such as the outer plate member and tarks, side pillars and side beams arranged in the circumferential direction of the vehicle body, but almost all the pressure load applied to the outer plate member is borne by the bone member. . Therefore, there is a problem in that the bone member increases in weight in order to have sufficient strength and rigidity against a pressure load.

た。Further, in the prior art, since the frame whose inner surface at the upper corner is formed and reinforced in a round shape and the frame whose inner surface at the lower corner is formed and reinforced in a round shape are alternately arranged, the frame is formed and reinforced in a round shape. There was a problem that the strength of the missing part was insufficient.
