Description

  The present invention relates to a structure of a railway vehicle having a swing type door.

  In railcars, side sliding doors are provided at passenger entrances and exits, through-passages serving as passenger passages and passages between vehicles, and partition walls between cabins and crew compartments are provided with swing doors. . The swing type door is attached to a side structure or a wife structure of a vehicle body via a hinge.

  Conventionally, in order to attach the swing type door to the vehicle body, with the door aligned with the vehicle body, a hinge mounting tap is processed on the vehicle body, or wind or water is blown from the gap between the door and the vehicle body. It was necessary to perform various operations such as adjusting the attachment of the seal rubber to prevent intrusion. For this reason, it took some time (for example, half a day) to install the door. In particular, since installation of electrical equipment and wiring work are performed over a long period of time in the cab, it is difficult to adjust the electrical process and the door mounting process.

  On the other hand, in Patent Document 1, for rationalization of work, an interior unit having a through door and a window portion can be fastened to a vehicle body part with a bolt, and the interior unit is assembled at a location different from the body part. It is disclosed to perform work and adjustment work.

Japanese Patent No. 3303318

  However, when the interior unit is assembled separately from the vehicle body portion as disclosed in Patent Document 1, the weight of the interior unit is relatively heavy, so that it is difficult to connect to the vehicle body portion. In addition, the wiring work can be performed only after the interior unit is coupled to the vehicle body portion, and there is a restriction on the timing of the electrical process as compared with the case where the entire vehicle body is assembled on site. Furthermore, with respect to the swing type door disposed on the vehicle body other than the interior unit, it is necessary to perform tapping and adjustment of the seal member at the site as in the conventional case.
