[Purpose] The present invention provides a side airbag unit with inflator-equipping housing wherein an inflator is attached with a housing which discharges gas in a desired and specific direction where the airbag inflates and deploys; and the thrust generated in a direction opposing the direction of the discharge gas flow can be suppressed should thermal damage to the inflator result in accidental gas discharge. [Means] The present invention comprises a sub-housing 6, an inflator 5 secured in the sub-housing, a 1st orifice 12 in the sub-housing positioned in proximity to gas guide ports and substantially facing an airbag deployment direction, a 2nd orifice 13 in the sub-housing separated an appropriate distance from the 1st orifice along an circumferential direction of the sub-housing, and a plug 7 sealing the 2nd orifice, wherein the plug is of thermo-soluble resin, and includes a nipple part 7b which is contact with an internal periphery of the 2nd orifice and a flange part 7a which extends from the nipple part and contacts with an internal surface 6a of the sub-housing. |
