Abstract of the Disclosure An air bag device for an assistant driver's seat comprises: a container having an opening for expanding an air bag on the front surface and intake ports for inletting air on the side surfaces; a lid covering the opening; valve plates provided in the container for closing the intake ports by being overlapped on the side surfaces and opening the intake ports by being separated therefrom; an air bag accommodated in the container in the folded state; a gas generator fixed on the rear surface portion of the container facing to the opening; first gas ejecting holes for ejecting gas toward the front surface of the container and second gas ejecting holes for ejecting gas toward the valve plates; and sealing means attached on the gas generator for sealing the first and second ejecting holes. The sealing means opens only at first gas ejecting hole portions when ejected gas pressure in the gas generator exceeds first predetermined pressure thereby allowing the gas to pass through the first gas ejecting holes to be ejected toward the front surface of the container. The sealing means opens further at the second gas ejecting hole portions when ejected gas pressure exceeds a second gas pressure higher than the first gas pressure thereby allowing the gas to pass through the second gas ejecting holes to be ejected toward the valve plates. When only the first ejecting holes open, the valve plates are pushed with the atmospheric air thus allowing the air to flow in the container through the intake ports. When the first and second ejecting holes open, gas passing through the second ejecting holes causes the valve plates to move near the intake ports thereby reducing the amount of the air flowing in the container.
