To provide a collective joint with improved efficiency of drainage.SOLUTION: A collective joint comprises an upper connection pipe having a horizontal connection part on an outer peripheral surface, and a tubular lower connection pipe 19 where an axis line O is provided along a vertical direction. The lower connection pipe 19 has a socket into which a lower end of the upper connection pipe is inserted, a swirl vane integrally provided with an inner surface of the lower connection pipe 19 by injection molding, and an inclined pipe part 32 whose diameter gradually decreases as it goes from top to bottom. An inner peripheral surface of the inclined pipe part 32 has a first inner surface 32a inclined so as to approach the axis line O gradually as it goes from top to bottom, a second inner surface 32b provided on a lower portion of a lower surface of the swirl vane, and a third inner surface 32c extending to an outer side in a radial direction from an end of a second side X2 on the second inner surface 32b, and facing the second side X2. In the outer peripheral surface of the inclined pipe part 32, a position of the outer peripheral surface corresponding to the second inner surface 32b is recessed, and the third inner surface 32c is inclined toward a first side X1 as it goes downward.SELECTED DRAWING: Figure 2
【課題】排水の効率を向上した集合継手を提供する。【解決手段】外周面に横管接続部を備えた上部接続管と、管状に形成され、軸線Ｏが上下方向に沿うように配置された下部接続管１９と、を備え、下部接続管１９は、上部接続管の下端が挿入される受口と、射出成形により下部接続管１９の内面と一体に設けられた旋回羽根と、上方から下方に向かうに従い漸次縮径する傾斜管部３２を有し、傾斜管部３２の内周面は、上方から下方に向かうに従い漸次、軸線Ｏに接近するように傾斜した第１内面３２ａと、旋回羽根の下面の下方の部分に配置された第２内面３２ｂと、第２内面３２ｂにおける第２側Ｘ２の端から径方向外側に延び、第２側Ｘ２を向く第３内面３２ｃを有し、傾斜管部３２の外周面のうち、第２内面３２ｂに対応する部分の外周面は凹んでおり、第３内面３２ｃは、下方に向かうに従い第１側Ｘ１に向かうように傾いている。【選択図】図２
