Abstract
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.
