DRAIN PIPE JOINT
To provide the drain pipe joint capable of maintaining drainage performance by forming a swirling flow and a ventilation core.SOLUTION: The drain pipe joint 100 comprises: a main pipe 10 that extends axially and is formed of a resin, and branched pipes 20A, 20B, 20C that communicate with the main pipe 10 and extend radially outward from a side surface of the main pipe 10 and are made of resin, wherein a plurality of swirl vanes 38, 58 are provided along an inner circumferential surface of the main pipe 10 so as to be separated in an axial direction, projection figures A, B obtained by respectively projecting at least two of the plurality of swirling blades 38, 58 among the plurality of the swirling blades 38, 58 onto a plane orthogonal to the axial direction overlap each other, and an area of an overlapping portion C of the projection figures A, B of two swirl vanes is 40% or more of the area of the projection figures A, B of respective swirl vanes 38, 58.SELECTED DRAWING: Figure 2
【課題】旋回流及び通気芯を形成して、排水性能を維持することができる排水管継手を提供する。【解決手段】排水管継手１００は、軸線方向に延び、樹脂で形成された本管１０と、本管１０に連通して、本管１０の側面から径方向の外側に延び、樹脂で形成された分岐管２０Ａ，２０Ｂ，２０Ｃと、を備え、本管１０の内周面に沿って、軸線方向に離間して複数枚の旋回羽根３８，５８が設けられ、複数枚の旋回羽根３８，５８のうち少なくとも２枚の旋回羽根３８，５８を軸線方向と直交する面へそれぞれ投影した投影図Ａ，Ｂは、互いに重なり、２枚の旋回羽根の投影図Ａ，Ｂの重なり部分Ｃの面積は、それぞれの旋回羽根３８，５８の投影図Ａ，Ｂの面積の４０％以上であることを特徴とする。【選択図】図２
