1. A gas generator comprising:
- a metallic housing having a closure shell and an initiator shell;
a filter provided throughout an inner circumference of the housing in a circumferential direction;
a combustion chamber which is provided in the housing and in which gas generants for generating a high-temperature gas by combustion are housed; and
an ignitor device which is attached to the initiator shell and ignites and burns the gas generants in the combustion chamber,and further comprising;
an igniting agent filled container which has the ignitor device therein and is filled with igniting agents; and
a cylinder body which is provided inside of the initiator shell and of which an inner wall is adhered to the whole outside of the igniting agent filled container,wherein the combustion chamber is formed of a space surrounded by an inner wall of the initiator shell, an inner wall of the closure shell, an inner wall of a filter material and an outer wall of the cylinder body,the cylinder body has flame spouting ports for spouting flame of the igniting agents into the combustion chamber on a side surface, andparts corresponding to the flame spouting ports of the cylinder body of the igniting agent filled container are ruptured by an impact when the igniting agents are ignited by the ignitor device.

Abstract
A gas generator includes a shortened cylindrical housing constituted by a lower lid that is an initiator shell including an ignitor device, and an upper lid which is a closure shell for closing the lower lid. Additionally, in the housing, an ignitor device, gas generants, and a filter material are arranged in this order from the center. The ignitor device includes an igniting agent filled container including an igniter and igniting agents therein, and a cylinder body provided in a state adhered to an outside surface of the igniting agent filled container. The gas generator is capable of stabilizing an ignition performance by a simple constitution.
