The present invention relates to a jamming prevention device for a door of a railway vehicle and, more specifically, a jamming prevention device for preventing jamming in a door of a railway vehicle which is opened or closed as a pair of main bodies of the railway vehicle door moves to the opposite sides. The jamming prevention device for a door of a railway vehicle comprises a body frame (110) installed in the main body (200) of the railway vehicle door; an elastic unit (120); and a wire unit (130).
