The present invention provides an airbag device for, upon collision of a vehicle carrying the airbag device with an obstacle, mitigating the impact of collision of the obstacle with an inflated airbag. The airbag device includes a bag housing case and a cover. A main airbag and a cover opening bag are housed in deflated, folded states within the bag housing case. First, the cover opening bag inflates by the inflow of gas, opening the cover. Gas also flows into the main airbag through the cover opening bag, thereby inflating the main airbag. If an obstacle collides with the inflated main airbag, a bag pressure release mechanism provided at the bottom of the bag housing case opens the main airbag, releasing gas within the main airbag and mitigating the impact on the obstacle.
