To provide a cleaning port joint capable of enhancing cut-off performance of a lid body mounted at a cleaning port part, and preventing water leakage from the cleaning port part in high-pressure cleaning.SOLUTION: A cleaning port joint comprises: a joint body having a cleaning port part formed into a cylindrical shape; a lid body mounted to the cleaning port part; and an annular seal member provided between an inner peripheral surface of the cleaning port part and an outer peripheral surface of an insertion part inserted into the cleaning port part of the lid body. The cleaning port joint also comprises: a rib having at least one cycle length, inclined and formed on an outer peripheral surface of the insertion part on a center side of the joint body with respect to the seal member so as to sequentially approach a center of the joint body; and a groove having at least one cycle length, inclined and formed on the inner peripheral surface of the cleaning port part so as to sequentially approach the center of the joint body, and fitted to the rib.SELECTED DRAWING: Figure 2
【課題】掃除口部に装着される蓋体の止水性能を高め、高圧洗浄時に掃除口部から水漏れすることを防止する掃除口継手を提供する。【解決手段】円筒状に形成され掃除口部を有する継手本体と、前記掃除口部に対して装着される蓋体と、前記掃除口部の内周面と前記蓋体の前記掃除口部に挿入する挿入部の外周面との間に設けられる環状のシール部材とを備える掃除口継手であって、前記挿入部の前記シール部材よりも前記継手本体の中心側の外周面に前記継手本体の中心に漸次近づくように傾斜して形成された少なくとも１周の長さを有するリブを備え、前記掃除口部の内周面に前記継手本体の中心に漸次近づくように傾斜して形成され前記リブに嵌合する少なくとも１周の長さを有する溝を備える。【選択図】図２
