The invention belongs to the technical field of automobile parts, and particularly relates to a steering intermediate shaft dust cover sealing structure which comprises a steering intermediate shaft and a front wall plate assembly, the steering intermediate shaft penetrates out of the front wall plate assembly, the steering intermediate shaft is provided with a dust cover assembly, the dust cover assembly is connected with the front wall plate assembly, and the front wall plate assembly is connected with the steering intermediate shaft. The dustproof cover assembly comprises a dustproof cover and a sealing assembly, one end of the dustproof cover is fixedly connected with the front wall plate assembly, the other end of the dustproof cover is connected with the steering intermediate shaft, and the sealing assembly is arranged in the dustproof cover and connected with the steering intermediate shaft in a sealed mode. The invention aims to solve the problem that the sealing effect is not ideal due to the fact that liquid pollutants are easy to enter an engine compartment from a gap between a sealing element and a dust cover and a gap between the dust cover and a bearing when the existing sealing element is used for sealing in the background technology.
