An air bag is formed of a panel portion with a gas introducing port, a partition wall situated inside the panel portion for partitioning an inside of the panel portion into a first chamber located on a front side of an automobile and a second chamber located on a rear side of the automobile, a gas passage situated between the first chamber and the second chamber, and at least one vent hole formed in the panel portion at the second chamber. An air bag device includes, in addition to the air bag, a retainer for retaining the air bag, an inflator for expanding the air bag, and a lid for covering the retainer. In case a collision speed is small or the passenger is relatively small, the passenger can be received by the air bag with a soft touch. In case the collision speed is large or the passenger is large, the passenger can be securely received by the first and second chambers.
