<P>PROBLEM TO BE SOLVED: To provide a rolling stock that can be constituted in light weight and low cost in comparison with the metal material, while securing high rigidity equivalent to the metal material. <P>SOLUTION: The rolling stock 100 maintains the shape of the rolling stock 100, is formed of a metal frame for raising rigidity (door reinforcement frame 200, upper frame 202, and lower frame 204) and FRP (Fiber Reinforced Plastics) and includes an outer casing structure 102 which constitutes a surface of the outside in the rolling stock 100. When a rolling stock 100 comprises the outer casing structure 102, the outer casing structure 102 is formed by fixing the metal frame to a position of an inner surface, or formed by incorporating the metal frame at a position between an inner surface and an outer surface. <P>COPYRIGHT: (C)2012,JPO&INPIT |
