Abstract

An airbag device includes an airbag, an airbag cover and a holder for holding the airbag and airbag cover. The airbag cover includes a door that is openable around a hinge at airbag deployment, and a side wall that is disposed around the door and attached to the holder. A functional component is held by a holding member and disposed in the door. The holding member includes a distal-side connecting portion that is fixed to the functional component, a root-side connecting portion that is secured to the holder, and a deformable portion that is disposed between the distal-side connecting portion and the root-side connecting portion. The deformable portion is configured to be plastically deformed at airbag deployment while having the distal-side connecting portion keep holding the functional component and suppressing a centrifugal force of the functional component from acting on the hinge of the door of the airbag cover.
