<p><P>PROBLEM TO BE SOLVED: To provide branching to a plurality of branch pipes mainly by one pipe joint, and to freely select the branching number. <P>SOLUTION: In a branching part structure 12 of a water feed pipe 13, a pipe joint body 21 to be fused to a water feed pipe 13 is provided and the pipe joint body 21 has a cylindrical projection part 24 for branch connection for connecting water feed branch pipes 11. A plurality of cylindrical projection parts 24 for branch connection are provided from the pipe joint body 21. Each of the plurality of cylindrical projection parts 24 for branch connection has a closing part 31 on its fore end, and is selectively used by opening the closing part 31 on its fore end only for the cylindrical projection part 24 for branch connection for connecting the water feed branch pipes 11. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
