COUPLING STRUCTURE OF RAILCAR

摘要

PROBLEM TO BE SOLVED: To provide a link structure of a railcar that can reduce noise owing to columnar resonance generated in space of coupling between railcars during high-speed travel as well as have simplified structure which does not interfere with operations such as maintenance. SOLUTION: In a space A of a coupling structure of railcars formed by coupling the periphery of the center connection aisle 3 between the railcars connected with each other using inner bellows 4 via a coupling device 25, protruding frame bodies 6A, 6B are vertically installed at both sides of the inner bellows 4 between opposite end surfaces of the car bodies in the state where the position of a partition plate 6 having the leading end at right angle is varied in a concavo-convex manner.
