To provide a gas fuel supplying device capable of detecting that gas fuel is discharged from a safety valve to the outside of a system.
This gas fuel supplying device supplying gas fuel to a gas engine through a gas supplying passage 3 comprises a pressure reducing means (a pressure reducing valve 4) reducing the pressure of gas supplied to the gas engine to be a specified pressure, and a safety valve 5 provided downstream from the pressure reducing means (the pressure reducing valve 4) and discharging the gas fuel in the gas supplying passage to release the pressure in the gas supplying passage 3. In a discharging path (a discharging pipe 6) discharging the gas fuel released by the safety valve 5, a discharge detecting means (a pressure sensor 8) for detecting discharging of the gas fuel is provided.
