To provide a drain pipe joint that is made from synthetic resin but enables improvement of a drainage capacity and prevention of back flow to a horizontal branch pipe.SOLUTION: A drain pipe joint 1 includes an upper connection member 10 and a lower connection member 30 that are coupled to an upper part of a joint member 20 and a lower part of the joint member 20, respectively. The upper connection member 10 comprises a guide pipe 12 having an upper revolving blade 16 for applying revolving force to drainage water. The lower connection member 30 is a cylindrical body whose whole body has a funnel shape having a diameter reducing as it goes downward, and comprises a lower revolving blade 31 for mainly receiving and applying revolving force to drainage water guided by the upper revolving blade 16. The joint member 20 is formed so as to have a diameter slightly larger than that of the guide pipe 12 and receives internal fitting of the guide pipe 12. A lower end of the guide pipe 12 is formed so as to be positioned below an upper part of a horizontal branch pipe HT connected to the joint member 20, and a lower end peripheral edge 13a of the guide pipe 12 (guide body 13) is formed so as to deviate downward as it goes from an outer peripheral surface to an inner peripheral surface.SELECTED DRAWING: Figure 3
【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３０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、前記誘導管１２の下端を前記継手部材２０に連結される前記横枝管ＨＴの上部よりも下方に位置するとともに、前記誘導管１２（誘導本体１３）の下端周縁１３ａを外周面から内周面に行くに従い下方に偏倚するように形成する。【選択図】 図３
