An air bag wherein a peripheral wall portion on one side opposite to an opening for introducing an inflation gas is put on the side of a peripheral wall portion having the opening and flattened. The peripheral edges around the opening are folded together closer to the opening side at the first stage. Peripheral edges on the end portion side thus folded around the opening are folded at the second stage in such a manner as to set the peripheral edges closer to the opening side whereby to house the air bag in a casing. The region of an air bag cover which is positioned above and substantially closer to a center of the air bag thus folded up is thick-walled so that the region thereof may protrude downward from the periphery of the air bag.
