摘要： An airbag device that can efficiently suppress an injury value for an occupant in an emergency includes a frontal airbag cushion that is expanded at a vehicle front side of a driver's seat and a curtain airbag cushion that is expanded at an outer side of the frontal airbag cushion in a vehicle width direction. The frontal airbag cushion includes an inner bag that is expanded by receiving a gas, inner vents that are disposed in the inner bag to discharge the gas, an outer bag that contains the inner bag therein and is expanded by receiving the gas from the inner vents and outer vents that are disposed in the outer bag to discharge the gas. A distance between the inner bag and the curtain airbag cushion is smaller than a width of a head of an occupant.
