Abstract: An airbag device which contributes to reducing an impact on an occupant, while minimizing a loss in inflation gas. The airbag includes first and second inner tethers each having a front panel coupled to a stationary portion around the inflator and a rear panel coupled to an occupant side of the airbag to control a shape into which the airbag is deployed. First and second vent holes are formed on left and right sides of the airbag, first and second opening/closing members capable of opening/closing the first and second vent holes, a first opening/closing tether having an opening/closing end portion coupled to the first opening/closing member and a coupled end portion coupled between the front panel and the rear panel of the first inner tether. A second opening/closing tether having an opening/closing end portion coupled to the second opening/closing member and a coupled end portion coupled between the front panel and the rear panel of the second inner tether. When the airbag is in a fully deployed state, under tension of the first and second opening/closing tethers, the first and second vent holes are closed by the first and second opening/closing members. When the occupant moves into the airbag, at least one of the first and second inner tethers is deformed (warped or bent) to move at least one of the first and second opening/closing tethers toward the corresponding vent hole and cause at least one of the first and second opening/closing members to open the corresponding vent hole.
