PROBLEM TO BE SOLVED: To provide a drain pipe connection device that easily attaches or detaches a drain pipe and does not allow a fastening nut firmly fixing a flange member to be loosened even if an unexpected circumferential force is applied thereto.SOLUTION: The drain pipe connection device that connects a drain port to a drain pipe comprises a flange member that is connected to the drain port; a fastening nut that is screwed into the flange member to fasten the flange member to the drain port at an abutting position against the lower end of the drain port; and a connecting member that is connected to the fastening nut to indirectly connect the flange member to the drain pipe. A protruding part is formed on either of the inner peripheral face of the connecting member and the outer peripheral face of the fastening nut, and a guide groove is formed on the other. The guide groove comprises: a horizontal guide part functioning as a lock position of the protruding part; an introduction guide part that accepts the protruding part and guides it to the horizontal guide part; and a lock part that binds the protruding part to the horizontal guide part. The horizontal guide part is disposed to surround the whole periphery of the other of the connecting member and the fastening nut.SELECTED DRAWING: Figure 3
【課題】 排水管の着脱が容易であり、かつ、予期せぬ周方向の力がかかった際も、フランジ部材を固定している締結ナットが緩まない排水管接続装置を提供すること。【解決手段】 排水口と排水管とを接続する排水管接続装置であって、排水口と接続されるフランジ部材と、フランジ部材に螺合し排水口の下端に当接する位置で、フランジ部材を排水口に締結する締結ナットと、締結ナットに接続され、フランジ部材と排水管とを間接的に接続させる接続部材と、を備え、接続部材の内周面および締結ナットの外周面のいずれか一方には突起部が、他方にはガイド溝が、形成されており、ガイド溝は、突起部のロック位置である水平ガイド部と、突起部を受け入れ、水平ガイド部に案内する導入ガイド部と、突起部を水平ガイド部に拘束するロック部と、を有し、水平ガイド部は、接続部材および締結ナットのいずれか他方の全周にわたって周設されていることを特徴とする排水管接続装置。【選択図】 図３
