To disclose one embodiment having a constitution which can reduce a pressure loss generated at a three-way joint, in the three-way joint having a first opening part, a second opening part and a third opening part.SOLUTION: A bulkhead part 12 is arranged in a position opposing a third opening part 11C via a space out of a passage 11D of a pipe main body 11. The bulkhead part 12 has a wall face which extends to the third opening part 11C from an inner wall face which connectively continues from a first opening part 11A and a second opening part 11B, and intersects with an opening center axial line of the first opening part 11A and an opening center axial line of the second opening part 11B. By this constitution, in a three-way joint 10, the bulkhead part 12 may function as a guide member for converting a circulation direction of liquid. Also, since the occurrence of "a disturbance of a flow of a vortex or the like" may be suppressed in the three-way joint, the generation of a large pressure loss in the three-way joint may be suppressed.SELECTED DRAWING: Figure 4 【課題】 第１開口部、第２開口部及び第３開口部を有する三方継ぎ手において、当該三方継ぎ手で発生する圧力損失を低減することが可能な構成の一例を開示する。【解決手段】 管本体１１の通路１１Ｄ内のうち第３開口部１１Ｃと空間を介して対向する位置に隔壁部１２が設けられている。当該隔壁部１２は、第１開口部１１Ａ及び第２開口部１１Ｂから連接する内壁面から当該第３開口部１１Ｃに向けて延び、かつ、第１開口部１１Ａの開口中心軸線及び第２開口部１１Ｂの開口中心軸線と交差する壁面を有する。これにより、当該三方継ぎ手１０では、隔壁部１２が液体の流通方向を転向させる案内部材として機能し得る。延いては、三方継ぎ手内で「渦等の流れの乱れ」が発生することが抑制され得るので、当該三方継ぎ手にて大きな圧力損失が発生することが抑制され得る。【選択図】図４
