In an air bag having a gas introducing opening for gas from an inflator, a synthetic resin molded member is provided on each face of a marginal portion of the gas introducing opening, and the synthetic resin molded members are coupled to each other. One of the synthetic resin molded members is formed with protrusions, and the other synthetic resin member has engaging holes corresponding to the protrusions. The protrusions are inserted in the engaging holes through holes formed through a cloth portion of the air bag, and welded to the engaging holes.
