Although it is possible to reinforce the periphery of the mounting hole of the mounting portion by pressing it against the mounting portion of the bag body, an increase in cost due to the increase in parts is unavoidable. If the above-mentioned special plate is not used (when the mounting part is directly attached to the body side part using the bolts and clips that are inserted into the mounting hole), the reaction force when deploying the airbag will cause it to tear from the mounting hole. May occur and progress, and the mounting part may break.

る。Further, when the present invention is carried out, the high proof stress portion is provided so as to surround the mounting hole (claim 2).
In the case of the invention according to (1), even if the occurrence of tears around the mounting hole is irregular, the progress of tearing from the mounting hole can be stopped. Further, when the high load bearing portion is composed of a plurality of bands (in the case of the invention according to claim 3), the reaction force at the time of airbag deployment can be dispersed and received in each band,
It is possible to prevent the concentration of stress at the mounting portion of the airbag bag, and to properly prevent the occurrence and progress of breakage from the mounting hole.

生じ難い。In the case where the high yield strength portion is woven with a higher density weaving yarn than the weaving yarn of the general portion of the airbag bag base cloth (in the case of the invention according to claim 4), one kind of weave is used. The airbag bag body can be woven using a thread, which can be handled only by changing the weaving method. Further, when the high load bearing portion is woven with a thicker yarn than the weaving yarn of the general portion of the airbag bag base cloth (in the case of the invention according to claim 5), the general portion of the airbag bag base cloth is woven. It is possible to reduce the difference in the width of the texture between the high-strength part and the high-proof portion, and there is little perforation caused by the deviation of the texture, and the chance of tearing is less likely to occur.
