The present invention provides a gas generator, including: a tubular housing, an ignition device attached to one end of the tubular housing, a diffuser portion having a gas discharge port and being attached to the other end of the tubular housing,in the tubular housing,a first combustion chamber defined by a first perforated-plate member on one end side in the tubular housing and filled with a first gas generating agent,a tubular member disposed in the remaining inner space of the tubular housing and having a communication hole on a peripheral wall portion thereof, a second-perforated plate member disposed between the first perforated-plate member and the tubular member, a second combustion chamber defined by the tubular member and filled with a second gas generating agent,the tubular member being disposed so that a gap is formed between the peripheral wall portion of the tubular housing and the tubular member, the tubular member having a first opening end portion abutting against the inner peripheral surface of the tubular housing in the side of the first perforated-plate member and a second end portion supported in the side of the diffuser portion.

1. A gas generator, comprising: a tubular housing, an ignition device attached to one end of the tubular housing, a diffuser portion having a gas discharge port and being attached to the other end of the tubular housing,in the tubular housing,a first combustion chamber defined by a first perforated-plate member on one end side in the tubular housing and filled with a first gas generating agent,a tubular member disposed in the remaining inner space of the tubular housing and having a communication hole on a peripheral wall portion thereof, a second-perforated plate member disposed between the first perforated-plate member and the tubular member, a second combustion chamber defined by the tubular member and filled with a second gas generating agent,the tubular member being disposed so that a gap is formed between the peripheral wall portion of the tubular housing and the tubular member, the tubular member having a first opening end portion abutting against the inner peripheral surface of the tubular housing in the side of the first perforated-plate member and a second end portion supported in the side of the diffuser portion. 2. A gas generator according to claim 1, wherein the tubular member includes an enlarged diameter part provided with an increased diameter at an opening portion in a side of the first opening end portion and a central hole at the center of a bottom surface in a side of the second end portion,a cup-shaped gas diverting member having a communication hole on a peripheral wall portion and a projection on a bottom surface is disposed in the side of the diffuser portion so that an opening portion of the gas diverting member is oriented toward the diffuser portion,the enlarged diameter part of the tubular member abuts against the inner peripheral surface of the tubular housing, andthe central hole of the tubular member is fitted to the projection on the bottom surface of the gas diverting member. 3. A method of assembling the gas generator according to claim 2, comprising: a step of attaching a cup-shaped gas diverting member, having a communication hole on a peripheral wall portion and a projection on a bottom surface, inside a tubular housing, the tubular housing including a diffuser portion having a gas discharge port attached to the other end so that an opening portion of the gas diverting member is oriented toward the diffuser portion;a step of attaching a tubular member so that an outer peripheral surface of an enlarged diameter part of the tubular member abuts against an inner peripheral surface of the tubular housing and a central hole of the tubular member fits to the projection on the bottom surface of the gas diverting member;a step of filling the tubular member with a predetermined amount of a second gas generating agent while tapping the tubular housing;a step of press-fitting a second perforated-plate to form a second combustion chamber filled with the second gas generating agent;a step of press-fitting a first perforated-plate member;a step of charging a first gas generating agent so as to abut against the first perforated-plate member; anda step of attaching an ignition device. 4. A method of assembling the gas generator according to claim 1, comprising: a step of attaching a tubular member inside a tubular housing to which a diffuser portion having a gas discharge port is attached on the other end;a step of filling the tubular member with a predetermined amount of a second gas generating agent from one end of the tubular housing while tapping the tubular housing;a step of press-fitting a second perforated-plate member from one end of the tubular housing to form a second combustion chamber filled with the second gas generating agent;a step of press-fitting a first perforated-plate member from one end of the tubular housing;a step of charging a first gas generating agent from one end of the tubular housing so as to abut against the first perforated-plate member; anda step of attaching an ignition device to one end of the tubular housing.
