TECHNICAL FIELD The present invention relates to a railway vehicle,
In particular, the present invention relates to a railcar without door pockets, in which doors are arranged so as to be opened and closed outside the side wall of the body structure.

[0002]

2. Description of the Related Art
In railcars and the like, there is known a railcar without a door pocket by arranging an entrance / exit door so as to open and close outside the side wall of the body structure. Since the door pocket is not used in this manner, it is not necessary to construct inner bones in the door bag, and the structure is simplified and the weight is reduced.

However, when such a structure is adopted in a passenger vehicle, as shown in FIG. 13, the vehicle window has to be a fixed window, and there is a problem that the window cannot be opened and closed. In addition, if a descending window is installed in such a vehicle without a door pocket, the descending window storage portion pops out into the vehicle compartment and presses the interior space of the vehicle.

Therefore, an object of the present invention is to prevent the interior space of a railroad vehicle having such a door pocket-less structure from being narrowed even if a descending window is installed.

Means for Solving the Problems, Embodiments of the Invention, and Advantageous Effects of the Invention A railway vehicle according to the present invention is a railway vehicle without a door pocket, in which an entrance / exit door is arranged so as to be opened / closed outside a side wall of a vehicle body structure. The side wall of the structure has a concavo-convex structure so that the side wall of the structure is dented at the opening / closing portion of the door and swelled at the window frame mounting portion. Further, a descending window having a bulge on the side wall of the structure as a storage portion is attached. And
It is characterized in that the depression amount of the side wall of the structure is set such that the entrance / exit door does not extend beyond the bulge of the side wall.

According to the present invention, since the side wall of the body structure has the concavo-convex structure that swells at the window frame mounting portion, the swelling portion can be used to store the descending window so that the storage portion does not pop out into the vehicle. A descending window can be installed. Further, by setting the amount of depression of the side wall of the structure to an amount that does not allow the entrance door to protrude beyond the bulge of the side wall, the reference of the vehicle limit can be taken by this bulge portion, and the interior space of the vehicle is not pressed.

As described above, the present invention solves the above-mentioned problems when a railcar without a door pocket is applied to a passenger vehicle, based on an unprecedented idea that the side wall of the vehicle body has an uneven structure. The present invention may be applied to vehicles other than passenger vehicles.
