Railway vehicle and through-passage side guard plate

The invention discloses a railway vehicle and a through-passage side guard plate. The through-passage side guard plate comprises a guard plate body, a left rotary support and a right rotary support. The left rotary support and the right rotary support are mounted on the left side and the right side of the guard plate body respectively. Each of the left rotary support and the right rotary support comprises a guide shaft. The guard plate body, the left rotary support and the right rotary support can slide relatively along the guide shafts and rotate relatively around the guide shafts, so that side rolling of the vehicle and transverse and longitudinal movement of the vehicle can be realized. During use, the left side and the right side of the guard plate body only bend slightly, rotating and curling deformation is avoided, bending deformation of the two sides of the inner guard plate around the rotation center axis of a vertical vestibule is reduced, and a comfortable riding environment is provided for passenge
