Inflator
First Claim
1. An inflator comprising a cylindrical housing charged with a pressurized gas and an ignition means for discharging high temperature gas inside the cylindrical housing, wherein the cylindrical housing has the interior formed in a single space and the gas discharge ports at both ends;
- gas flow paths to respective ventilation channels are closed by rupturable plates;
the ignition means is mounted on a portion of the cylindrical housing between the end portions; and
the ignition means is separated from the interior of the cylindrical housing by a single rupturable plate.

Abstract
The present invention provides an inflator with high operation reliability. A first rupturable plate 47 is broken by high temperature gas generated from a gas generating agent ignited and burnt by an igniter 43, and the high temperature gas flows into interior spaces 16a, 16b to increase an internal pressure in the interior spaces. As a result, two second rupturable plates 26, 36 are broken by pressurization, so that the pressurized gas is jetted from the gas discharge holes 25, 35.
