  • Patent number: 10870409
    Abstract: A gas generator includes a housing, a partition member which divides a space in the housing into a combustion chamber where a gas generating agent is accommodated and a filter chamber where a filter is accommodated, and a sealed container which externally seals the gas generating agent. The filter has a hollow portion which reaches an axial end surface located on a side of the combustion chamber. The sealed container is made of a member relatively low in mechanical strength so as to burst or melt as a result of burning of the gas generating agent. The partition member is made of a member relatively high in mechanical strength such that only a portion opposed to the hollow portion bursts as a result of burning of the gas generating agent to provide a communication hole which allows communication between the combustion chamber and the filter chamber with each other.
