In case of emergency such as a side crash of the vehicle, when gas from the inflator flows quickly forward through the gas inlet passage and reaches the closed end at the front end of the gas inlet passage, the internal pressure in the gas inlet passage increases. Then, gas is blown from the gas exhaust ports into the airbag and the airbag is inflated and deployed. At this moment, the gas exhaust ports open in the direction along the inner surface of the side portion the vehicle body, so that gas is blown from the gas exhaust ports in the same direction and the airbag is inflated and deployed downwardly like a curtain along the inner surface of the side portion of the vehicle body. In this inflation and deployment of the airbag, the airbag is inflated and deployed quickly, smoothly and reliably in a relatively narrow space between the inner surface of the side portion of the vehicle body and the passenger.
