Abstract
When an air bag body beings to expand due to gas flowing from an inflator into the air bag body, a left side folded piece and a right side folded piece which have been folded into concertinas expand quickly to thrust laterally to the left and right. Vent holes are located to be exposed in upper faces of the folded pieces. Accordingly, the gas can flow out from the interiors of the folded pieces through the vent holes as soon as the folded pieces begin to expand.
