The invention discloses a sealing structure suitable for a double-leaf sliding plug door of an inter-city and urban motor train unit, and belongs to the technical field of sliding plug doors of rail transit vehicles. The sealing frame is fixedly connected with the vehicle body profile; the auxiliary locks are arranged on the two sides of the sealing frame, and the door plate is pressed through the auxiliary locks; wherein rubber strips are distributed in the circumferential direction of the door plates, the rubber strips at the center joint position of the two door plates are in butt joint in an embedded mode, and the sealing frame and the rubber strips are of an integrally-formed structure. The sliding plug door is reliable in structure and good in sealing performance, the airtight index requirement of a whole vehicle at the speed grade of 200 km/h for a sliding plug door system is met, and the requirement of the whole vehicle at the speed grade of 200 km/h for the airtight index of the sliding plug door system under the large passenger flow volume is met. In addition, the sealing structure can adapt to vibration and impact influences caused by the fact that vehicles with the speed grade of 200 km/h run under the working condition AW3.
