PROBLEM TO BE SOLVED: To safely supply a gas without deteriorating the purity of the gas in a cylinder by connecting a cylinder valve to one of two openings, and connecting a gas takeout unit consisting of the cylinder valve and a pressure reducting valve to the other opening, and housing the bomb in a container. SOLUTION: Cylinder valves 6a, 6b are mounted on two opening parts arranged on both ends of a gas cylinder 2, respectively. A pressure reducting valve 8 is arranged on the gas supplying-side cylinder valve 6a through, for example, a diaphragm type pressure gauge 10 to form a takeout unit U, which is connected to a gas supplying piping 25, and the cylinder valve 6b is used for gas filling. Gas sampling simplex tubes 13 extended from an alarm 11 are inserted to a space 7 and a section 9, respectively, to regularly monitor gas leakage. Accordingly, a high-pressure gas part which is apt to cause the gas leakage is contracted and also limited within a container, so that this device is operated as a highly safe supplying device.
