The utility model discloses a contact type sealing structure applied to a rotary air pre-heater, which is used for sealing a dynamic gap between a moving part and a stationary part in the air pre-heater. The sealing structure at least comprises a sealing member; the sealing member comprises a main body and a filament fixed on the main body and arranged in a cluster shape; the filament comprises afixed end part connected with the main body and a free end part with elasticity; the sealing member is fixedly connected with one of the moving part and the stationary part through the main body; andthe free end part of the filament is in a contact state with the other part by means of elasticity. Because the filament arranged in a cluster shape is arranged in the position of the dynamic gap in the air pre-heater, the technical purpose of reducing the air leakage rate of the air pre-heater is achieved by utilizing the flow characteristic of air in the filament arranged in a cluster shape andthe elastic characteristic
