Abstract
An airbag to be inflated by gas for a vehicle includes a base member for the airbag, an opening and closing vent provided in the base member, and a discharging gas control member for restraining gas from discharging from the opening and closing vent. The discharging gas control member closes or slightly opens the opening and closing vent when an occupant does not contact a front surface of the airbag facing the occupant when the airbag is inflated. The discharging gas control member opens or widely opens the opening and closing vent so as to allow the gas to be discharged from the opening and closing vent when the occupant contacts the front surface of the airbag, and the front surface is pushed in a direction opposite to the occupant.
