A gas leakage preventing unit of an LPG(Liquefied Petroleum Gas) fuel injecting device is provided to prevent LPG fuel gas from leaking out while injecting the fuel gas into a vehicle. A gas leakage preventing unit of an LPG fuel injecting device comprises a support member(10) supporting a spring(20); a valve(40) elevated and operated by the elastic force of the spring; and a protrusion member(30) mounted at the outer side of the support member to guide settling of the spring. The spring operates the valve to an original position by the elastic force after injecting gas into a vehicle. The protrusion member is formed on the support member to limit a movement width of the spring so as to prevent the spring from being defectively attached on the upper end of the support member due to sliding.
