The invention relates to the technical field of commercial vehicles, and discloses a fuel tank cap with a dustproof function, which comprises a fuel tank cap body, a rubber sealing ring for sealing the fuel tank cap body and a filling port is arranged in the fuel tank cap body, and a metal pressure plate is arranged on the rubber sealing ring. An air inlet with a downward opening is formed in the lower side of the fuel tank cap body, an air channel communicated with the air inlet is formed in the fuel tank cap body and is in an inverted U shape, one end of the air channel is communicated with the air inlet, and the other end of the air channel is communicated with an air outlet formed in the bottom of the fuel tank cap body. According to the fuel tank cap with the dustproof function, dust, water and impurities are effectively prevented from entering a fuel tank, and the fuel tank is effectively prevented from being shrunken due to blockage of an air vent of the fuel tank cap.
