A leak fuel gas ventilation system of vehicle is provided that the explosion accident due to the gas remaining is prevented and the electrical energy consumption can be reduced since the fuel gas leaking in the fuel bombe is completely discharged to outside. A leak fuel gas ventilation system of vehicle comprises a fuel tube(2) supplying the fuel, a container which is formed in the connection part between the fuel tube and fuel bombe, and which collects the fuel gas, a ventilation tube(4) which is connected to container while surrounding the fuel tube, and a path(5) formed between the ventilation tube and fuel tube. The path includes a resonant unit(11) of which inside is filled with the air while having the air port(12) heading to the vehicles outside, a vibrator(13) which is formed in one side of the resonant unit, and which vibrates the resonant unit, an air current generation means(10) generating the fast air current ejection.
