  In the configuration described above, since the heating device and the front end of the seat are close to each other, high-temperature hot air blown out from the heating device flows to the feet of the sitting passenger. Thereby, there exists a possibility of giving a passenger discomfort.

  In addition, the space below the seat is reduced by the heating device. For this reason, when a passenger puts a luggage under the seat, the luggage may not be able to enter under the seat and go out to the aisle side. A passenger who sits takes his / her feet toward the center of the aisle with the luggage that has been placed on the aisle side, which causes trouble for the standing passenger.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a railway vehicle in which a heating device is arranged below the seat so that passengers can be made uncomfortable and a sufficient space can be formed below the seat. .

  The railway vehicle of the present invention includes a vehicle main body having a side structure extending in the longitudinal direction of the vehicle, a seat having a backrest disposed in the vehicle main body so as to face the side structure, the seat, and the vehicle main body. And a heating device attached to the side structure.

In the said structure, a heating apparatus can be arrange | positioned in the innermost part under a seat by attaching a heating apparatus to a side structure. Thereby, the distance of a heating apparatus and the leg of the passenger who sits can be made longer than before. With such a configuration, a large amount of air (secondary air) is mixed before the hot air blown out from the heating device reaches the feet of the passengers, so the temperature of the hot air decreases. As a result, hot air having a suitable temperature flows to the passenger's feet, so that passengers can be prevented from feeling uncomfortable.
Further, by arranging the heating device at the innermost position below the seat, a sufficient space for storing luggage can be formed below the seat. If the luggage can be stored under the seat, the seated passenger does not raise his / her legs toward the center of the passage due to the luggage, so that the standing passenger is not disturbed.
Further, by attaching the heating device to the inner side surface of the side structure, it is possible to omit the lining plate and / or the baseboard of the side structure where the heating device is attached.

  In addition, the heating device includes a heating element, a cover member that covers the heating element together with the side structure, and a reflector that is disposed at a position sandwiching the heating element between the cover member in the vehicle width direction. It is preferable that the cover member has a plurality of holes formed in a portion facing the heating element in the width direction of the vehicle.

  By arranging the reflector and the heating element in the vehicle width direction, the infrared rays emitted from the heating element can be reflected not toward the floor of the vehicle but toward the passage (the center in the width direction of the vehicle). Thereby, while being able to improve the heating effect in a vehicle rather than before, a passenger's step can be warmed.

  Furthermore, in the above configuration, it is preferable that the reflecting plate extends in the vertical direction. Since the infrared rays emitted from the heating element can be reliably reflected toward the passage by the reflecting plate extending in the vertical direction, the heating effect in the vehicle can be further improved and the feet of the passengers can be further warmed.

  Moreover, in the said structure, it is preferable that a part of inner surface of the said side structure is formed as the said reflecting plate. By using a part of the inner side surface of the side structure as a reflector, a simple configuration can be achieved.

  Furthermore, the seat further includes a stool disposed to face the floor surface, and the stool has a cushion part and a frame body that supports the cushion part from below, It is preferable that a hole penetrating in the vertical direction is formed in the frame body at a portion located above the heating device, and the cushion portion and the frame body are separable. By removing the cushion portion, the heating device can be easily repaired and inspected from the hole in the frame.

  According to the present invention, by disposing the heating device at the innermost position below the seat, it is possible to prevent passengers from being uncomfortable by the hot air blown from the heating device, and to form a sufficient space below the seat. can do.
