Abstract
An air bag includes a main body formed by sewing up the respective peripheries of two fabrics, a front panel and a rear panel with a thread, first tether belts and second tether belts for connecting the central portion of the front panel and the central portion of the rear panel. Each of the first tether belts has a low strength portion structured by forming notches on both sides. Stud bolts are inserted into through holes of the first tether belts, through holes of the air bag, bolt holes of the retainer, and bolt holes of a flange. The air bag deploys to the outside of the steering wheel quite rapidly in the initial stage of the deployment, and the front panel extends suitably forward in the latter stage of the deployment.
