The invention discloses a fuel tank cap with the stability effectively improved. The fuel tank cap comprises a fuel pipe connector and a fuel tank cap body. A fuel pipe is connected to the bottom of the fuel pipe connector, the fuel pipe connector is provided with an oil inlet channel, a connecting surface is arranged at the top end of the fuel pipe connector, and a fixing groove surrounding the fuel pipe connector by one circle is formed in the outer wall of the fuel pipe connector. The fuel tank cap body comprises a fixing part, a holding part is arranged on the top of the fixing part, the fixing part is arranged on the bottom of the fuel tank cap body, and a limiting device is arranged on the fixing part and comprises a packing block and an anti-rotation block. The packing block and the anti-rotation block are connected. The anti-rotation block is trapezoid and provided with an abutting surface connected with the packing block, and the abutting surface is connected with an inclined surface. According to the invention, the stability of the fuel tank cap is effectively improved, the fuel tank cap is prevented from sliding caused by loosening, and the problem that opening of the fuel tank cap is more difficult because the fuel tank cap is excessively rotated is prevented.
