PROBLEM TO BE SOLVED: To provide a wash stand that enables a drain pipe adaptor to be fixed on a drain port and suppresses water infiltration from a gap between the drain pipe adaptor and the drain port, regardless of a dimensional tolerance of the drain port.SOLUTION: A drain port connection structure includes a bowl part, a drain port 130, a drain pipe adaptor 160, and a fastening member 170. An inner peripheral surface 131 of the drain port 130 is squeezed in a downward direction. The drain pipe adaptor 160 includes a flange part 161, a groove formed along a periphery of a tip surface of the flange part 161, and an annular packing 180, the tip surface of the flange part 161 inclining inwardly in a radial direction of the drain pipe adaptor 160, so as to come into contact with an inner peripheral surface 131 of the drain port 130. While the drain pipe adaptor 160 inserted from above the drain port 130 is being fixed to the drain port 130 by the fastening member 170, the annular packing 180 comes in contact with the inner peripheral surface 131 of the drain port 130 and is flattened so as to fill a gap above the groove, thus keeping the drain port 130 and the drain pipe adaptor 160 water-tight.SELECTED DRAWING: Figure 3
【課題】排水口の寸法公差によらず、排水口に排水管アダプタを固定でき、かつ、排水管アダプタと排水口との隙間から水が浸入しにくい洗面台を提供する。【解決手段】ボウル部と、排水口１３０と、排水管アダプタ１６０と、締結部材１７０とを備え、排水口１３０の内周面１３１が、下方に向けて絞られており、排水管アダプタ１６０は、フランジ部１６１と、フランジ部１６１の先端面に周設された溝と、環状パッキン１８０とを有し、フランジ部１６１の先端面は、排水口１３０の内周面１３１と当接するように排水管アダプタ１６０の径方向内側に向かって傾斜しており、排水口１３０の上方から挿入された排水管アダプタ１６０が締結部材１７０によって排水口１３０に固定された状態において、環状パッキン１８０は、排水口１３０の内周面１３１と当接することで溝の上方の隙間を埋めるように潰されて排水口１３０と排水管アダプタ１６０とを止水しているもの。【選択図】図３
