1. An airbag device comprising: an airbag that inflates and deploys with gas to protect an occupant in a vehicle; and an inflator that supplies gas to the airbag, wherein the airbag includes an outer bag that protects the occupant by inflation and deployment thereof, an inner bag that is disposed in the outer bag and accommodates the inflator, and a connecting member that is disposed in the inner bag, wherein the inner bag inflates with the gas supplied from the inflator to become an inflated inner bag, and has a gas flow port to supply the gas to the outer bag and at least one tubular inflation portion protruding outward from the inner bag, wherein the outer bag inflates with the gas supplied through the gas flow port provided in the inner bag to become an inflated outer bag, wherein the connecting member is joined to an end of the tubular inflation portion and is connected to an inner surface of the outer bag, facing to the occupant through, the gas flow port, and wherein, as the outer bag inflates, the connecting member is drawn out of the gas flow port of the inflated inner bag to thereby draw the end of the tubular inflation portion into the inner bag and restrict movement of the outer bag in an occupant direction.
