PURPOSE: To provide a body of a rolling stock which is lighter in weight and capable of withstanding a variation in external pressure in a body of a rolling stock suitable for a rolling stock running at high speed and its manufacture.
CONSTITUTION: In a body of a rolling stock comprising a roof structure body 2, side structure bodies 1, end structure bodies, and an underframe 10, the underframe 10 is composed of a pair of side beams 11 arranged at both lateral sides of the body in longitudinal direction of a body and roughly horizontal lateral beams 12, mounted on a pair of side beams, which are arranged between a pair of side beams 11 and, as viewed from the end of the body in longitudinal direction, support arc-shaped floor members 13 protruded downward and floor members from the underside. Because the body is provided with the arc-shaped floor members 13 protruded downward, variation in external pressure can be supported as a film stress inside a plane, and a whole body pressure resistance strength can be increased. Also members which are subject to variation in external pressure can be made thicker and lighter in weight.
