Abstract
When a gas generating agentinside a first combustion chamberis burnt, a gas generating agentis prevented from being burnt by function of a metal thin plateclosing a communication holewith a second combustion chamber. A cuphaving a holeis covered on an igniter, and the flame thereof advances into a transfer chargestraightly in a narrow width. Accordingly, since the transfer chargeis burnt completely, sufficient flame for burning a gas generating agentcan be generated securely. A communication holebetween a first combustion chamberand a second combustion chamberis closed by double-layered seal tapelaminated through an adhesive layer. After activation, the seal tapesare not ruptured due to increase in the internal pressure of the first combustion chamber, but they are peeled off easily due to increase in the internal pressure of the second combustion chamber
