Claim:
An airbag device comprising: an inflator; an airbag communicating with the inflator for undergoing inflation by a gas generated from the inflator; a holding member for holding the airbag in a state as folded and contained therein, and pressing down on an outer circumference of the airbag, to thereby restrain inflation and expansion of the airbag in a direction extending from a center of the airbag to the outer circumference of the airbag, caused by the gas generated from the inflator at least in an initial stage of the inflation of the airbag; and a gas rectification member for rectifying and guiding the gas generated from the inflator up to the vicinity of a part of the airbag, inflating in the initial stage of the inflation thereof, which is provided substantially at a central part of the airbag, wherein the holding member is formed to have a hole at the time of inflation of the airbag so that the airbag travels through the hole during inflation, wherein the gas rectification member is not attached to a part of the airbag which expands during the inflation of the airbag, wherein the airbag has a folded portion, wherein the folded portion of the airbag is provided between the holding member and the gas rectification member in a radial direction of the airbag during the initial stage of inflation, wherein the holding member is separate from an airbag cover, and wherein the opening in the holding member is sized to allow a part of the airbag cover to pass through the opening of the holding member.
