PROBLEM TO BE SOLVED: To provide a lifesaving floating body inflator solving the problem that since there is a fear that a difference of individual is caused in tightening strength because mounting of a gas cylinder relies upon feeling of a hand and an error is caused in distinguishing of the used and unused gas cylinder in the conventional lifesaving floating body inflator. SOLUTION: In the lifesaving floating body inflator, a gas cylinder single body and an indicator for a gas cylinder are combined to constitute a gas cylinder assembly. When the gas cylinder assembly is bonded to a cut device for opening a sealing plate of the gas cylinder, appropriate tightening of the gas cylinder is indicated by a color. When the sealing plate is opened by the cut device, a fact that the gas cylinder is used is indicated on the indicator for the gas cylinder by the color. COPYRIGHT: (C)2004,JPO
