PURPOSE:To obtain an air bag which has no bent hole. CONSTITUTION:An air bag which has no bent hole is formed by weaving at least two kinds of fabrics together, such as a high density fabric F1 of not less than 1500 of cover factor and of not less than 0.6 of fiber filling factor, which is woven by using a stretch-broken thread string including high power heat-resistant fiber of not more than 2 denier of single thread weaving degree, of not less than 16g/de of intensity, and of not lower than 300 deg.C of heat decomposition temperature, and a low density fabric F2 of not less than 700 of cover factor and of less than 0.6 of fiber filling factor, which is woven by using the stretch-broken thread string including the same fiber as the F1. |
