る。By the way, the airbag device is not limited to the one for the driver's seat, but in recent years, one for the passenger seat has been developed. A bag as shown in FIG. 9 has been conventionally used as an airbag bag body of the passenger side airbag device. The bag includes a body cloth (16) sewn in a cylindrical shape and the body cloth (1).
Approximately triangular side cloth (17) sewn on both sides of 6)
And a rectangular opening (18) is provided on a part of the peripheral surface of the cylindrical body cloth (16) to serve as a gas inlet of the inflator. Then, four retainer mounting portions (19) and (20), which are different from the main body cloth (16), are sewn to the main body cloth (16) in the opening (18) so as to form a bag shape. The retainer mounting portions (19) and (20) are fixed to the airbag case via a retainer (not shown) inserted therein.
