Abstract: The invention provides a hydrogen permeable structure, which can effectively prevent peeling-off of a hydrogen permeable film and hence has higher durability, and a method of manufacturing the structure. The hydrogen permeable structure has a hydrogen permeable film formed on the surface of or inside a porous support, having a thickness of not more than 2 &mgr;m, and containing palladium (Pd). The hydrogen permeable film is formed on the surface of or inside the porous support by supplying a Pd-containing solution and a reducing feed material from opposite sides of the porous support.

Abstract: 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.
