To provide a drain connection pipe for suppressing the filling of drain water in a drain flow path from a Western style toilet bowl in a renovated toilet bowl structure in which a Western style toilet bowl is installed using an existing Japanese style toilet bowl, and also suppressing the running out of sealing water in the Western style toil bowl.SOLUTION: A drain connection pipe 5 for connecting a drain port of the Western style toilet bowl installed using the existing Japanese style toilet bowl to a drain port of the Japanese style toil bowl, includes an upstream side vertical pipe part 31 to be connected at its upper side to the drain port of the Western style toilet bowl, and a horizontal pipe part 32 provided on the downstream side of the upstream side vertical pipe part 31 to form a right angle shaped upstream side bent part 38 together with the upstream side vertical pipe part 31, the horizontal pipe part 32 having a swollen portion 50 on the upstream side, of which the flow path cross section facing the internal of the flow path of the upstream side bent part 38 is expanded to the upper side.SELECTED DRAWING: Figure 4
【課題】既設の和風便器を利用して洋風便器を設置した改修便器構造における洋風便器からの排水流路において、排水の満水化を抑制し、洋風便器の封水切れを抑制する排水接続管を提供する。【解決手段】既設の和風便器を利用して設置された洋風便器の排水口を、和風便器の排水口に接続させる排水接続管５であって、上側を洋風便器の排水口に接続させる上流側縦管部３１と、上流側縦管部３１の下流側に設けられ、上流側縦管部３１とともに直角状の上流側屈曲部３８をなす横管部３２と、を備え、横管部３２は、その上流側に、上流側屈曲部３８の流路内に臨む流路断面を上側に広げた膨出部５０を有する。【選択図】図４
