Abstract
A gas generator includes a housing and a partition portion dividing a space in the housing into a combustion chamber accommodating a gas generating agent and a filter chamber accommodating a filter. The partition portion includes a first region which opens at the time of activation by being located to be opposed to a hollow portion of the filter and an annular second region which does not open even at the time of activation by being located to be opposed to a portion of an axial end surface of the filter except for the hollow portion. The second region is provided with a large-thickness portion constructed to be greater in thickness than the first region and opposed to an outer edge portion of the axial end surface of the filter, and the large-thickness portion is constructed to gradually be greater in thickness from an inner circumferential end portion toward an outer circumferential end portion.
