PURPOSE: A device for preventing the back flow of gas for an LPG bombe is provided to reduce the dangers of gas outflow by installing a ball valve at the inside of a valve housing even when a filling hose is damaged. CONSTITUTION: A valve housing(10) is L-shaped tube, and a first connecting unit(12) is formed at one side of the valve housing to be connected to an introducing tube(2). A second connecting unit(13) is formed at the other side of the valve housing to be connected to a flexible hose(7) with a connector(17). A valve chamber(14) is formed at the inside of the valve housing. A ball valve(15) installed at the inside of the valve chamber rises by fuel pressure when filling fuel and supplies fuel to the bombe through the introducing tube, and falls when finishing fuel filling and prevents the back flow of the gas.
