To provide a technique by which flow of combustion products such as combustion gas in a housing of a gas generator can be preferably controlled.SOLUTION: The gas generator has a first igniter and a second igniter, and comprises a first space into which a first gas generating agent which is combusted by the first igniter is charged, a second space into which a second gas generating agent which is combusted by the second igniter is charged, a bulkhead member that defines the inside of a housing and an inner cylinder member which stores the first igniter and has a communication part at one end part thereof. The gas generator further comprises a blocking member that blocks a third space formed between an inner wall surface of the inner cylinder member and an outer wall surface of a fixed part of the first igniter and communicated through a communication part to the first space, which is configured to be inhibited from deforming with respect to pressurization from the first space side and to be allowed to deform with respect to pressurization from the third space side so as to eliminate a blocked state between the first space and the third space.SELECTED DRAWING: Figure 1

    【課題】ガス発生器のハウジング内における燃焼ガス等の燃焼生成物の流れを好適に制御する技術を提供する。【解決手段】第1点火器及び第2点火器を有し、第1点火器により燃焼される第1ガス発生剤が充填される第1空間と、第2点火器により燃焼される第2ガス発生剤が充填される第2空間とを、ハウジング内を画定する隔壁部材と、第1点火器を収容し一端部に連通部を有する内筒部材とを備える、ガス発生器である。そして、ガス発生器は、内筒部材の内壁面と第1点火器の固定部の外壁面との間に形成され連通部から第1空間まで通じる第3空間を、第1空間側から閉塞する閉塞部材であって、第1空間側からの加圧に対してはその変形が阻害され、第3空間側からの加圧に対してはその変形が許容され第1空間と第3空間との間の閉塞状態を解消するように構成される閉塞部材を、更に備える。【選択図】図1
