<p>An object is to reduce costs and improve productivity with respect to a side airbag having a high pressure chamber and a low pressure chamber divided by a sewn portion, a diffuser that distributes gas for inflation to the high pressure chamber and the low pressure chamber, and a check valve that regulates flowing of gas from a high pressure chamber side to a low pressure chamber side. A partitioning wall (24), that divides a lower chamber (28) (high pressure chamber) and an upper chamber (30) (low pressure chamber) within a side airbag (16), is structured by a portion of a lower base cloth (32) (high pressure chamber base cloth) that structures the lower chamber (28) or a portion of an upper base cloth (34) (low pressure chamber base cloth) that structures the upper chamber (30). A check valve (24), that permits flowing of gas, jetted-out from a gas jetting-out portion (22A) of an inflator (22), from the upper chamber (30) to the lower chamber (28) and that regulates flowing of gas in an opposite direction, is provided integrally with the partitioning wall (18).</p> |
