Abstract
The present invention provides a gas generator including, an ignition device chamber, a gas inflow chamber, and a pressurized gas chamber being arranged from a first end fixed with an ignition device to a second end opposite thereto in a cylindrical housing, an inner circumferential wall surface of the cylindrical housing, from the ignition device chamber to the gas inflow chamber, having a first movement restricting portion, a second movement restricting portion and a stopping portion which are arranged in an axial direction at intervals in the above order so as to protrude, the second movement restricting portion having an ignition device chamber-side surface which is an inclined surface decreasing an inner diameter of the housing from the side of the ignition device chamber to the side of the gas inflow chamber and a gas inflow chamber-side surface whose angle (α1) with respect to the cylindrical housing is not more than 90 degrees, so that an axial cross-sectional shape of the second movement restricting portion is a triangle, a breaking device being arranged between the ignition device chamber and the gas inflow chamber and including a base whose outer circumferential surface …
