ABSTRACT:
In a railway car body formed of hollow shape members40, a hollow shape member51having a shock absorbing function is provided to the ends of a hollow shape member40constituting an underframe30, where impact load is most likely to be received. The hollow shape member40is positioned so that the longitudinal direction thereof is arranged along the longitudinal direction of the car body. When impact load is received, the hollow shape member51formed at the ends of the member40deforms and collapses, thereby relieving the impact force. The present invention simply provides treatment to some areas of the hollow shape members that form the car body without changing the conventional railway car structure greatly, thus minimizing the impact load provided to the passengers upon collision, and improves the safety of the railway car.
