PROBLEM TO BE SOLVED: To provide a body of a railroad car formed by hollow extruded shapes, in which a buffer structure part is provided internally within an extent not exceeding greatly the size of the structural member without using any particular additional member(s) to inside the body and the part under the floor. SOLUTION: The body of the railroad car formed from hollow shapes 40, in which a hollow shape member 51 having a buffer function is provided on the hollow shape 40 at the end of a base frame 30 having a high likelihood to receive a shock load. The hollow shape 40 has its longitudinal direction identical to the longitudinal direction of the body. When a shock load is applied, the hollow shape member 51 deforms and collapses so as to relieve the shock. This is accomplished only by processing part of the hollow shape structure without changing the existing body structure substantially, and the shock to passenger is relieved to the minimum even in the event of train collision, and the safety is enhanced.
