A plurality of side modules include a first module, a second module and a third module extending between the first module and the second module in the carbody longitudinal direction and joined to the first module and the second module. A lower end portion of the first module and a lower end portion of the second module oppose and are joined to a floor bodyshell. A lower end portion of a region of the third module opposes the floor bodyshell, the region being located between the first module and the second module. The lower end portion of the region of the third module is freer with respect to the floor bodyshell than the lower end portion of the first module and the lower end portion of the second module. The third module is supported by the floor bodyshell through the first module and the second module. |
