摘要： The present invention provides a gas generator in which an outer container is formed by a pressurized gas bottle and a gas generation chamber housing, and a closing member closes therebetween, a gas inflow chamber formed with a gas discharge port is provided between a gas generation chamber and a pressurized gas chamber, a partition wall provided with a rupturing member separates the gas inflow chamber from the gas generation chamber. The partition wall has a communication hole that makes communication between the gas generation chamber and the gas inflow chamber, an outer circumferential edge surface of the partition wall abuts against an inner circumferential wall surface of the outer container so as to make the partition wall movable in an axial direction, and the partition wall faces directly the closing member at a distance therefrom. The rupturing member has an outer diameter smaller than an inner diameter of the opening closed by the closing member and is formed at the partition wall so as to face directly the closing member at a distance therefrom. At a time of actuation, the partition wall moves in an axial direction while reducing a volume of the gas inflow chamber and is stopped by abutting against a step portion or a protrusion formed on the side of the gas generation chamber relative to the position where the gas discharge port is formed, the rupturing member breaks through the closing member to open a gas discharge path from the pressurized gas bottle, and the pressurized gas and the combustion gas from the gas generation chamber are discharged from the gas discharge port.
