PROBLEM TO BE SOLVED: To simultaneously use a plurality of gas appliances having different gas pressures with one gas cylinder, by supplying gas with a plurality of gas pressures from one gas cylinder.SOLUTION: A branch pipe 10 is constituted such that a downstream pipeline 12, which branches one gas passage formed by an upstream pipeline 11 into a plurality of gas passages, is connected to the upstream pipeline 11 connected to a gas supply pipe 32 of a gas cylinder 30. A low-pressure regulator 21 and an intermediate pressure regulator 22, in which adjusted gas pressures are different from each other, are connected to each of the plurality of downstream ends of the downstream pipeline 12. |
