Abstract
An airbag apparatus including a vent hole that is reliably opened when the pressure of an airbag has reached a predetermined level. An apparatus includes inner and outer bags placed in a retainer in folded conditions and the retainer is closed by a module cover. The retainer has a vent hole. The vent hole is closed by a lid or sheet type closing structure. The module cover is pushed open by the inflation pressure of the inner bag. The gas in the inner bag is discharged into the outer bag to inflate the outer bag. When the inner pressure of the outer bag has reached a predetermined level, the closing structure opens to open the vent hole.
