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 in a bayonet system; 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 part has a circumferential step part formed at an end part on a center side of the joint body. The lid body has an elastic flange part formed on an outer periphery of the end part of the insertion part on the center side of the joint body. The elastic flange part is positioned on the center side of the joint body in the step part.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バヨネット方式で装着される蓋体と、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、 前記掃除口部は、前記継手本体の中心側の端部に形成された円周状の段部を有し、前記蓋体は、前記挿入部の前記継手本体の中心側の端部の外周に形成された弾性フランジ部を有し、前記弾性フランジ部は、前記段部の前記継手本体の中心側に位置する。【選択図】図２
