Abstract

A passenger's side airbag device of the invention is formed of a case, an airbag, a lid, attachment members for connecting the lid to the case, and an inflator. In order to attach the lid to the case, leg portions are inserted into insertion openings of the attachment members and pressed downwardly. The leg portions hit outer projecting pieces at first, and move downwardly while being slightly bent inwardly. Then, the leg portions hit inner projecting pieces and move while being slightly bent outwardly. When the inner projecting pieces face first openings and the outer projecting pieces face second openings, the projecting pieces enter the openings, so that the lid is attached to the case. It is easy to attach the lid to the case.
