The invention discloses a steering dust cover structure which comprises a dust cover body. A clamping groove capable of being clamped on a vehicle body metal plate is circumferentially formed in the lower portion of the dust cover body and an interference lip which extends in the direction of the vehicle body metal plate and is in interference fit with the vehicle body metal plate is arranged at the portion, at the upper end of the clamping groove, of the dust cover body. Furthermore, an arc-shaped lip making linear contact with the lower bottom face of the vehicle body metal plate is arranged at the portion, at the lower end of the clamping groove, of the dust cover body. The steering dust cover structure is simple, stable and reliable, the requirement for the size of the vehicle body metal plate is lowered, the vehicle body metal plate of the small size can be pressed as well, and relative motion can not be generated when external force is received. In addition, the arc-shaped lip at the lower end of the clamping groove makes linear contact with the lower bottom face of the vehicle body metal plate, the sealing performance of the dust cover body and the vehicle body metal plate can be effectively improved, and the sealing performance of a whole dust cover is further improved in cooperation with the pressure exerted to the vehicle body metal plate by the interference lip.
