いという欠点を有していた。Further, in the one disclosed in Japanese Patent Publication No. 57-60166, the distance from the bolt mounting hole to the inner peripheral edge of the peripheral portion of the bag mounting opening can be made larger than before, so that a slight increase in strength can be expected. Since the structure described in this publication does not have the reinforcing cloth, the strength of the mounting portion cannot be satisfied only by the woven cloth of the bag body. This is because as long as it is a woven fabric, the woven yarn is cut short in a certain direction, and this portion does not increase the strength so much. Further, in this case, the diameter of the inner peripheral edge of the peripheral edge of the bag attachment port is not so large as to block the gas ejection port of the gas generator, and therefore the strength is not significantly increased due to the constraint condition from this aspect. It had the drawback of not being able to bite.

保護作用を妨げる懸念があった。Furthermore, in the one disclosed in Japanese Utility Model Laid-Open No. 61-185642, only the chain stitch provided on the peripheral portion of the bag attachment opening of one base cloth is a specific direction in which the base cloth is a woven fabric. Is weaker than other directions, and under conditions where the distance from the mounting holes such as bolts to the mounting port is small, such as at the peripheral edge of the bag mounting port, when the airbag expands suddenly in the radial direction. However, there is a concern that the peripheral portion of the bag attachment opening may break from the attachment hole and gas may leak, impeding the occupant protection function of the airbag device.
