The present invention provides an inflator suitable for use in a curtain air bag system or the like. A first passage 37 linking an ignition means chamber 30 and the interior of an inflator housing 20 is blocked by a first rupturable plate 38. The first rupturable plate 38 is formed integrally with a rod-form member 24. When an igniter 36 is activated, the first rupturable plate 38 is ruptured, thereby pushing the rod-form member 24 such that an arrowhead 24c of the rod-form member 24 ruptures a second rupturable plate 48. Pressurized gas is then discharged through gas discharge holes 46 to inflate the air bag. |
