PROBLEM TO BE SOLVED: To reduce inside flow resistance, by shortening the length of a secondary side gas pipe for connecting a branch pipe part and a gas apparatus. SOLUTION: A lead-in pipe part 11 of a gas outlet 1 is arranged obliquely downward. A primary side connecting part 13 connected with a primary side gas pipe G1 is arranged in a lower end part of the lead-in pipe part 11. The branch pipe part 12 branching off from the lead-in pipe part is arranged in the lead-in pipe part 11. The branch pipe part 12 is arranged obliquely upward. A secondary side connecting part 14 connected with the secondary side gas pipe G2 is arranged in an upper end part of the branch pipe part 12. The secondary side connecting part 14 is arranged above the primary side connecting part 13. COPYRIGHT: (C)2010,JPO&INPIT
