  • Publication number: 20220396232
    Abstract: An airbag device includes an airbag, a case in which the folded airbag is housed, and an airbag cover that covers the folded airbag. An attachment portion of the airbag cover is attached to a peripheral wall portion of the case by a rivet being caused to pass through. The case is such that a vicinity of a boundary region between the peripheral wall portion and a bottom wall portion is curved in an approximate arc in cross-section. The attachment portion includes a protruding portion that protrudes toward the peripheral wall portion side in an end edge farther to a leading end side than a region of penetration of the rivet.
