Abstract

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.

First claim

The invention claimed is:

1. A carbody of a railcar,
the carbody comprising:
a first bodyshell constituted by a side bodyshell divided into a plurality of side modules in a carbody longitudinal direction; and
a second bodyshell constituted by a floor bodyshell or a roof bodyshell, an end portion of the side bodyshell being joined to the second bodyshell, the end portion being located at one side in a vertical direction,
the plurality of side modules including:
a first module;
a second module provided away from the first module in the carbody longitudinal direction; and
a third module extending between the first module and the second module in the carbody longitudinal direction and directly joined to the first module and the second module, a length of the third module in the carbody longitudinal direction being longer than each of a length of the first module in the carbody longitudinal direction and a length of the second module in the carbody longitudinal direction,

an end portion of the first module and an end portion of the second module opposing and being joined to the second bodyshell, the end portions of the first and second modules being located at the one side,
an end portion of a region of the third module opposing the second bodyshell, the region being located between the first module and the second module in a side view, the end portion of the region being located at the one side, the end portion of the region of the third module being freer with respect to the second bodyshell than the end portion of the first module and the end portion of the second module, and
the third module being supported by the second bodyshell through the first module and the second module.

2. The carbody according to claim 1 , wherein an opening portion constituted by a window opening or a door opening is provided between the first module and the second module.

3. The carbody according to claim 2 , wherein:
the first bodyshell is provided with the window opening as the opening portion, a first door opening provided at one side of the window opening in the carbody longitudinal direction, and a second door opening provided at the other side of the window opening in the carbody longitudinal direction;
the first module is provided between the first door opening and the window opening;
the second module is provided between the second door opening and the window opening; and
the third module is provided under the window opening.

4. The carbody according to claim 3 , wherein:
the first module is provided at one side of the first door opening in the carbody longitudinal direction so as to define the first door opening; and
the second module is provided at one side of the second door opening in the carbody longitudinal direction so as to define the second door opening, the one side of the second door opening is opposite to the one side of the first door opening in the carbody longitudinal direction.

5. The carbody according to claim 4 , wherein:
the first module is a first door pocket module including a first door pocket that houses a door configured to open and close the first door opening; and
the second module is a second door pocket module including a second door pocket that houses a door configured to open and close the second door opening.

6. The carbody according to claim 4 , wherein:
the plurality of side modules further includes a fourth module provided at the other side of the first door opening in the carbody longitudinal direction so as to define the first door opening, the first door opening being sandwiched between the fourth module and the first module in the carbody longitudinal direction;
the second bodyshell includes
a longitudinal member constituted by a side sill or a cantrail and extending in the carbody longitudinal direction at one side in a carbody width direction, and
a door opening bracket fixed to the longitudinal member; and

the door opening bracket includes a joint portion to which the first module is joined and a joint portion to which the fourth module is joined.

7. The carbody according to claim 3 , wherein the third module is a wainscot panel module including a side outside plate located under the window opening.

8. The carbody according to claim 1 , wherein the end portion of the region of the third module is in a non-joined state with respect to the second bodyshell, the region being located between the first module and the second module in the side view.

9. The carbody according to claim 1 , wherein a gap is formed between at least a part of the end portion of the third module and the second bodyshell.

10. The carbody according to claim 9 , wherein the end portion of the third module opposes the floor bodyshell and is located lower than an upper end of a side portion of the floor bodyshell and located at a lateral side of the upper end of the side portion in the carbody width direction.

11. The carbody according to claim 9 , further comprising a sealing member inserted into the gap.

12. The carbody according to claim 1 , wherein the third module further includes a receiving member, an interior part including a seat member being attached to the receiving member.

13. The carbody according to claim 2 , wherein
the first bodyshell is provided with the window opening as the opening portion, a first door opening provided at one side of the window opening in the carbody longitudinal direction, and a second door opening provided at the other side of the window opening in the carbody longitudinal direction; and
the first, second and third modules are disposed between the first door opening and the second door opening.

14. The carbody according to claim 1 , wherein
a window opening is provided between the first module and the second module;
the third module includes a wainscot panel module and a window modesty panel module; and
the window opening is a rectangular space surrounded by the first module, the second module, the wainscot panel module and the window modesty panel module.

15. A carbody of a railcar,
the carbody comprising:
a first bodyshell constituted by a side bodyshell divided into a plurality of side modules in a carbody longitudinal direction; and
a second bodyshell constituted by a floor bodyshell or a roof bodyshell, an end portion of the side bodyshell being joined to the second bodyshell, the end portion being located at one side in a vertical direction,
the plurality of side modules including:
a first module;
a second module provided away from the first module in the carbody longitudinal direction; 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 length of the third module in the carbody longitudinal direction being longer than each of a length of the first module in the carbody longitudinal direction and a length of the second module in the carbody longitudinal direction,

an end portion of the first module and an end portion of the second module opposing and being joined to the second bodyshell, the end portions of the first and second modules being located at the one side,
