## Abstract

A side bodyshell of a railcar includes: an outside plate including a window opening; horizontal frames arranged below the window opening and joined to the outside plate; and a vertical frame crossing the horizontal frames in a manner to pass over a pier panel, which is lateral to the window opening. The vertical frame includes: a first flange joined to the outside plate at the pier panel; and a second flange spaced apart from the outside plate below the first flange such that a step is formed between the first flange and the second flange, the second flange being joined to the horizontal frames.

## Claims

### Claim 1

A side bodyshell of a railcar, the side bodyshell comprising:
an outside plate including a window opening;
horizontal frames arranged below the window opening and joined to the outside plate; and
a vertical frame crossing the horizontal frames in a manner to pass over a pier panel, which is lateral to the window opening, wherein
the vertical frame includes:
a first flange joined to the outside plate at the pier panel; and
a second flange spaced apart from the outside plate below the first flange such that a step is formed between the first flange and the second flange, the second flange being joined to the horizontal frames.

### Claim 2 (depends on 1)

The side bodyshell of a railcar according to claim 1, wherein
the outside plate includes at least a pair of the window openings adjacent to each other, and
the pier panel is positioned between the pair of the window openings.

### Claim 3 (depends on 1)

The side bodyshell of a railcar according to claim 1, wherein
no horizontal frames are disposed on the pier panel.

### Claim 4 (depends on 1)

The side bodyshell of a railcar according to claim 1, wherein
the outside plate includes at least two entrance openings,
the window opening is disposed between the entrance openings, and
the horizontal frames extend continuously from one of the entrance openings to the other entrance opening.

### Claim 5 (depends on 1)

The side bodyshell of a railcar according to claim 1, wherein
the vertical frame includes:
a vertical main wall extending parallel to the outside plate; and
a vertical side wall extending from an end portion of the vertical main wall and connecting to the first flange and the second flange, and
a gap is formed between the first flange and the second flange in a direction in which the vertical main wall extends.

### Claim 6 (depends on 5)

The side bodyshell of a railcar according to claim 5, wherein
a reinforcing member is fixed to the vertical frame, the reinforcing member including a reinforcing wall, the reinforcing wall spanning between the first flange and the second flange and facing the vertical main wall.

### Claim 7 (depends on 5)

The side bodyshell of a railcar according to claim 5, wherein
the first flange, the second flange, and the vertical side wall are provided on each of both sides of the vertical main wall.

### Claim 8 (depends on 5)

The side bodyshell of a railcar according to claim 5, wherein
each of the horizontal frames includes:
a flange joined to the outside plate;
a horizontal main wall spaced apart from the outside plate and facing the outside plate; and
a horizontal side wall extending from an end portion of the horizontal main wall and connecting to the flange, and
through-holes are formed in the vertical main wall of the vertical frame at positions where the vertical main wall overlaps the flanges of the respective horizontal frames.

### Claim 9 (depends on 1)

The side bodyshell of a railcar according to claim 1, wherein
a lower portion of the outside plate and a lower portion of the vertical frame are bent to be offset inward in a width direction of the railcar.

### Claim 10 (depends on 5)

The side bodyshell of a railcar according to claim 5, wherein
a distance from the vertical main wall to the first flange is greater than a distance from the vertical main wall to the second flange.
