摘要： A carbody support device of a railway vehicle, including support mechanisms installed between a front bogie and a carbody and between a rear bogie and the carbody in a traveling direction, and supporting the carbody against the respective bogies. The support mechanisms regulate both the front bogie and the rear bogie inclining in the same vehicle width direction with respect to the carbody when the railway vehicle travels through a curve, while the support mechanisms permit the front bogie and the rear bogie inclining in different vehicle width directions.

摘要： A restricting member is configured to restrict abnormal rising of a carbody when an air spring expands by a predetermined amount or more. The restricting member includes: a base portion; a contact portion provided at the base portion and configured to be brought into contact with a lower surface of a bogie frame when the air spring expands by the predetermined amount or more; and a temporary fastening portion formed at the base portion. The temporary fastening portion is configured to be attachable to and detachable from a temporary fastened portion formed at a side surface of a center pin extending downward from a carbody.

摘要： A railway vehicle stopper includes a first rigid member, a second rigid member, a rubber elastic body, a third rigid member, an abutting member, and a communication passage. The second rigid member is arranged opposed to the truck frame or the vehicle body with an interval. The rubber elastic body elastically couples the supporting portion of the first rigid member to the second rigid member. The third rigid member is mounted inside the supporting portion of the first rigid member to form an air chamber with the second rigid member. The abutting member is coupled to at least one of mutually opposed surfaces of the second rigid member and the third rigid member. The communication passage is provided on one or both of the first rigid member and the third rigid member to communicate the air chamber with an outside.
