To provide a drain pipe joint excellent in drainage performance.SOLUTION: A drain pipe joint 10 includes: a vertical cylindrical pipe body 12 having an upper pipe connection portion 14 and a lower pipe connection portion 20; and a horizontal pipe connection portion 24 branching sideward from the pipe body. A deflection plate 32 is formed on an inner peripheral surface of the pipe body. The deflection plate has a shape expanding toward an axial center of the tube body in a plan view, and its upper surface 32b is formed in a convex shape that is highest at the center of a base end and becomes lower toward a protruding end 32a. An edge portion 32d having a right angle or an acute angle is formed on a boundary circumference edge between the protruding end and a lower surface 32c of the deflection plate.SELECTED DRAWING: Figure 2
【課題】排水性能に優れる排水管継手を提供する。【解決手段】排水管継手１０は、上管接続部１４と下管接続部(２０)とを有する縦筒状の管本体(１２)、および管本体から側方に分岐する横管接続部２４を備える。管本体の内周面には、偏流板３２が形成される。偏流板は、平面視で管本体の軸中心に向かって膨らむ形状を有し、その上面(３２ｂ)は、基端中央部が最も高く、突出端(３２ａ)に向かって低くなる凸状に形成される。偏流板の突出端と下面(３２ｃ)との境界周縁には、直角または鋭角のエッジ部(３２ｄ)が形成される。【選択図】図２
