To provide a rolling stock body structure suitable for reduction of the generation of noise in a vehicle, in a rolling stock structure body, especially a rolling stock running at a high speed.
In a rolling stock structure body formed such that a bed frame formed of a hollow section having surface materials 61 and 62 made of a light alloy and a truss material 63 to interconnect the surface materials, a side structure body, a roof structure body, and an end structure body are combined together for joining protrusion parts 66 are formed on at least the surface materials 61 on the inside of a car of the surface materials 61 and 61. This constitution provides a rolling stock structure body which is reduced in weight, improves pressure resistance, and is excellent in an effect to reduce the generation of noise in a vehicle.
