The retainer 4 has a bottom surface portion 41 for supporting an airbag 2 and an inflator 3, a side wall portion 42 that is disposed at the outer periphery of the bottom surface portion 41 and that has a height set to H so that the side wall portion 42 hardly receives a pressure of the airbag 2 when the airbag 2 is inflated and developed, and engagement members 43 that are disposed on the side wall portion 42 and that are engageable with the holding holes 53. The substantially entirety of the retainer 4 is housed in the inner case 52 when the engagement members 43 are engaged with the holding holes 53. |
