The outer cloth and the inner cloth of the umbrellalike body are coupled by a plurality of coupling cords , and when the gas is filled, the outer cloth and the inner cloth generate curved surfaces toward the same direction. Also the inflator ignites an ignition device by pulling a tractive cord , and a gas producing agent within a gas producing chamber explodes and the gas is jetted from a jet.
