<p><P>PROBLEM TO BE SOLVED: To provide a branch pipe member high in workability and low in cost. <P>SOLUTION: The branch pipe member includes a body 310 having a branch 316 in which a branch flow passage is formed in the middle of a barrel 311 having a main flow passage therein, a cap nut 320 installed at one connection port 312 of the main flow passage, and a connection hose 330 connected to a connection port of the branch flow passage via a fixing metal piece 331. A connection screw 315 and a flange 317 are provided at an outer circumference of the other connection port 313 of the body. Holding parts 318 which are projected over the outer circumference of the flange 317 are formed at both sides of the barrel 311 of the body. Thus, the branch pipe member 300 can be constituted by a simple structure. The cost can be reduced thereby, and screw fastening work can be executed while holding the holding part 318 by a tool during the screw fastening work. Any co-rotation can be prevented during the fastening work, and the screw can be fastened reliably. Execution accuracy is enhanced thereby, and the occurrence of water leakage or the like can be suppressed. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
