PURPOSE: An inflater for a dual stage air bag is provided to easily open a plug divider with little force when secondary pressurized gas is generated by placing a hinge towards the second ignition device through cutting a half of the plug divider. CONSTITUTION: First and second ignition devices(10a,10b) are installed at both ends of an inflater. The first and second ignition devices(10a,10b) oxidize first and second gas agent(16a,16b). When the first and second gas agent(16a,16b) are oxidized by the first and second ignition devices(10a,10b), first and second propelling devices(11a,11b) push pressurized gas to an exterior. The first and second gas agent(16a,16b) are divided by a plug divider(12a). The plug divider(12a) pushes a spring(15) when secondary gas is generated so as to provide a route for discharging gas. Pressurized gas generated from the first and second gas agent(16a,16b) is filtered by a filter(13). A discharging port(14) is formed for filling pressurized gas in an air bag cushion.
