To provide a drain pipe joint capable of improving drainage capacity and preventing backflow to a lateral branch pipe while being made of synthetic resin.SOLUTION: A drain pipe joint 1 is formed by connecting an upper connecting member 10 to an upper part of a joint member 20 and a lower connecting member 30 to a lower part of the joint member 20, respectively. The upper connecting member 10 comprises a guide pipe 12 having an upper swirl vane 16 that imparts a swirling force to drainage, the lower connecting member 20 is a funnel-shaped cylindrical body whose diameter decreases as it goes downward, and comprises a lower swirl vane 31 that mainly receives the drainage guided by the upper swirl vane 16 and imparts a swirling force. The joint member 20 is formed to have a diameter one size larger than that of the guide pipe 12, and fits the guide pipe 12 inside. A ridge control guide 17 extending vertically below the upper swirl vane 16 is provided on a lower inner peripheral surface 13b of the guide pipe 12, and the control guide 17 controls the drainage flowing downward from the guide pipe 12 not to flow into a lateral branch pipe HT.SELECTED DRAWING: Figure 2
【課題】 合成樹脂製でありながら排水能力の向上及び横枝管への逆流防止を可能にした排水管継手を提供する。【解決手段】 継手部材２０の上部に上部連結部材１０を、継手部材２０の下部に下部連結部材３０をそれぞれ結合してなる排水管継手１であって、上部連結部材１０は排水に旋回力を付与する上部旋回羽根１６を有する誘導管１２を備え、下部連結部材２０は全体が下方に行くに従い縮径する漏斗状をした筒体で、前記上部旋回羽根１６に誘導された排水を主に受け止めさらに旋回力を付与する下部旋回羽根３１を備え、継手部材２０は誘導管１２よりも一回り大径に形成されて誘導管１２を内嵌し、誘導管１２の下部内周面１３ｂに上部旋回羽根１６よりも下方に上下方向に伸びる突条の制御ガイド１７を設け、制御ガイド１７で誘導管１２から下方に流下する排水を横枝管ＨＴに流入しないように制御する。【選択図】 図２
