RAILROAD VEHICLE AND PLUG DOOR FOR RAILROAD VEHICLE

摘要

Provided are: a railroad vehicle that efficiently moves a door to an airtight position and makes it possible to maintain the air tightness of the door without increasing the size of a cylinder device even when the door must be moved across a distance to arrive at the airtight position; and a plug door for a railroad vehicle. When a door (8) moves to the position that is indicated by the two-dot/dash line in FIG. 1 , a piston (32) extends in the vehicle width direction, a pressing member (33) is brought into contact with the inner surface of the door (8), and the door (8) is moved toward a door frame (W) (in the vehicle body width direction). Due to the fact that an auxiliary pressing device (30) brings the piston (32) into perpendicular contact with the inner surface of the door (8), it is possible to efficiently move and press the door (8) without increasing the size of a cylinder device even when the door must be moved across a distance to arrive at an airtight position. In addition, the main pressing device (40) that is indicated in FIGS. 5(a)-5(b) is subsequently used to further press the door (8) toward the door frame (W).
