Summary:PROBLEM TO BE SOLVED: To provide a compact ventilation-integrated joint installed between a vertical drain pipe and a horizontal pipe, capable of reducing negative pressure in draining time, capable of smoothly draining water while preventing clogging by securing a flow by a swirling flow in draining time even in the case of the pipe having risk of reducing carrying force, and capable of surely preventing reduction and stopping of the valve function by a backflow of drain water.SOLUTION: A ventilation-integrated joint comprises a vertical drain pipe connection part 24 and a horizontal pipe connection part 27 provided in an eccentric position to the axis P of this vertical drain pipe connection part 24, and ventilates in draining time via a vent valve part 40 provided on the inside of a joint body 20. The vent valve part 40 normally holds a closing state without projecting from the upper end of the joint body 20, and when the joint body 20 becomes negative pressure, a valve element 31 of the vent valve part 40 is openably driven to the inner side of the joint body 20. A shielding part 50 is provided for shielding a bore hole 52 formed in a valve stem storage part 41 provided in the vent valve part 40.SELECTED DRAWING: Figure 1 【課題】排水立て配管と横配管との間に設置して排水時の負圧を軽減でき、搬送力が低下するおそれのある配管の場合にも、排水時の旋回流による流れを確保して詰まりを防ぎながらスムーズに排水でき、かつ排水の逆流による弁機能の低下や停止を確実に防止できるコンパクトな通気一体型継手を提供する。【解決手段】排水立て配管接続部２４とこの排水立て配管接続部２４の軸芯Ｐに対して偏心位置に設けた横配管接続部２７とを有し、継手本体２０の内部に設けた通気弁部４０を介して排水時に通気するものである。通気弁部４０は、通常は、継手本体２０の上端より突出することなく閉止状態を保持し、継手本体２０が負圧になったとき、通気弁部４０の弁体３１が継手本体２０の内方側へ開放駆動する。通気弁部４０に設けた弁軸収容部４１に形成した穿孔穴５２を、遮蔽する遮蔽部５０を設けている。【選択図】図１
