The present invention relates to a structure for preventing eccentricity in a variable gauge of a railway vehicle. More particularly, the present invention relates to a structure for preventing eccentricity in a variable gauge of a railway vehicle, which is configured to smoothly unlock a locking mechanism while maintaining a vertical angle with an axle without a flange being eccentric even if one side of the flange is pushed by an unlocking rail, when the railway vehicle equipped with a variable gauge wheelset system is driven in a gauge change section by using an eccentricity prevention member provided in a bogie frame of the railway vehicle. 본 발명은 철도차량의 궤간가변 편심방지구조에 관한 것으로, 보다 상세하게는 철도차량의 대차프레임에 구비되는 편심방지부재를 이용하여 궤간 가변 윤축 시스템을 갖춘 철도차량이 궤간변환 구간을 주행하는 경우, 해정 레일에 의해 플랜지의 한쪽이 밀리더라도 플랜지가 편심되지 않고 차축과 수직한 각도를 유지하면서 원활하게 잠금기구를 해정하도록 구성된 철도차량의 궤간가변 편심방지구조에 관한 것이다.
