An airbag device to reduce an expansion pressure is provided to supply a superior adjustment function of an expansion pressure of a cushion by selectively closing a vent hole. An airbag device includes a cushion(20), an inflator(22), a gas distribution guide(24), a gas induction tube(26), a stopper(28), and a tether(29). The cushion is provided with a vent hole(20a). The inflator generates a gas for the expansion of the cushion. The gas distribution guide distributes a gas from the inflator. The gas induction tube connects the gas distribution guide to the vent hole. The stopper closes an inlet(26a) of the gas induction tube in the gas distribution guide. The tether allows the stopper to selectively prevent the inlet of the gas induction tube.
