1. An airbag mounting structure comprising:
- a retainer having a protrusion formed at a bottom thereof and protruding outward, and at least one concavity formed in the bottom thereof to be curved inwardly in a half-circular configuration coaxial with the protrusion and extending to a side face of the retainer, said protrusion extending in a longitudinal direction of the retainer and having an inflator-through hole in at least one of ends thereof in the longitudinal direction and a half-cylindrical configuration, an airbag having a portion inserted into the protrusion and at least one opening confronting the inflator-through hole, and an elongated inflator inserted into said portion of the airbag positioned inside the protrusion through the inflator-through hole of the retainer and the at least one opening of the airbag, and having a substantially cylindrical configuration and an end, said end being inserted through the inflator-through hole, projecting outside the protrusion and engaging the concavity at the bottom of the retainer so that the airbag is clamped between an inner surface of the protrusion and an outer surface of the inflator.

Abstract
An airbag mounting structure allows an airbag to be easily mounted to a retainer and provides reduced stress exerted onto the retainer during the inflation of the airbag. The retainer is provided with a protrusion and the concavities in the bottom thereof. An inner plate which is disposed inside the airbag has a downward projection. A portion between slits of the airbag is pressed into the protrusion by the downward projection. An inflator is inserted into the protrusion from a side end of the retainer and the both ends of the inflator are engaged with concavities.
