To provide a collective joint with improved drain efficiency.SOLUTION: A collective joint comprises an upper connection pipe comprising a horizontal pipe connecting part on an outer peripheral surface, and a lower connection pipe 19 formed into a tubular shape and arranged so that an axial line O is 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 from the top to the bottom. An inner peripheral surface of the inclined pipe part 32 has a first inner surface 32a that is inclined so as to gradually approach the axial line O from the top to the bottom, and a second inner surface 32b arranged at a lower portion of the lower surface of the swirl vane.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、を有する。【選択図】図２
