DRAIN VALVE DEVICE AND WASHING WATER TANK DEVICE EQUIPPED WITH THE DRAIN VALVE DEVICE
To provide a drain valve device capable of improving sealing performance between a valve seat part and a drain valve body even when a drain part body is fixed to a drain port part by a fixing part so as to generate a load toward a bottom surface of a washing water tank on a flange part.SOLUTION: A drain part body of a drain valve device comprises: a valve seat part 78; an inner cylinder part 52 that extends downward from an inner portion of the valve seat part; and a flange part 154 that protrudes outward from a side surface of the inner cylinder part on a lower side of the valve seat part, and is placed on a bottom surface of a washing water tank around a drain port part, wherein the drain part body 148 is fixed to the drain port part 10 by a fixing part 158 so as to generate the load directed to a bottom part of the washing water tank on the flange part, the drain part body 148 has a vertical rib 176 that connects the valve seat part and the flange part in a vertical direction, and an inclined rib 194 that is formed to connect the valve seat part and the flange part, and extends diagonally along an outer peripheral direction of the inner cylinder part 52.SELECTED DRAWING: Figure 4
【課題】排水部本体が、鍔部に上記洗浄水タンクの底面に向かう荷重を生じさせるように固定部により排水口部に固定される場合においても、弁座部と排水弁体とのシール性能を向上できる排水弁装置を提供する。【解決手段】本発明の排水弁装置の排水部本体は、弁座部７８と、弁座部の内側部分から下方側に延びる内筒部５２と、弁座部の下方側において内筒部の側面から外側に突出すると共に、排水口部の周りの洗浄水タンクの底面上に配置される鍔部１５４と、を備え、排水部本体４８は、鍔部に洗浄水タンクの底部に向かう荷重を生じさせるように固定部１５８により排水口部１０に固定され、排水部本体１４８は、弁座部と鍔部との間を上下方向に接続する縦リブ１７６と、弁座部と鍔部とを接続するように形成される傾斜リブ１９４は、内筒部５２の外周方向に沿うように斜めに延びる、傾斜リブ１９４とを備えている。【選択図】図４
