DRAIN VALVE DEVICE, FLUSH WATER TANK DEVICE WITH DRAIN VALVE DEVICE, AND FLUSH TOILET BOWL WITH FLUSH WATER TANK DEVICE
PROBLEM TO BE SOLVED: To provide a drain valve device to be installed on a flush toilet bowl with a relatively low silhouette, the drain valve device having a shorter valve body main shaft and a lower overall height.SOLUTION: A drain valve device 28 includes: a valve body 48 that opens/closes an exhaust port as a valve body main shaft is lifted; a float mechanism 52 for low-intensity flushing that includes a cam engaging part 94 on a low-intensity flushing side to be engaged with the valve body main shaft and a float 96 for low-intensity flushing, where the cam engaging part on the low-intensity flushing side is disengaged from the valve body main shaft as the float for low-intensity flushing is lowered; a float mechanism 54 for high-intensity flushing where a cam engaging part on a high-intensity flushing side is disengaged from the valve body main shaft as a float for high-intensity flushing is lowered; and a casing part. The valve body main shaft 76 is provided with one common protrusion 80 engaged with the cam engaging part 114 on the high-intensity flushing side when the valve body main shaft 76 has been lifted by a lifting amount for a high-intensity flushing mode, and engaged with the cam engaging part 94 on the low-intensity flushing side when the valve body main shaft has been lifted by a lifting amount for a low-intensity flushing mode.SELECTED DRAWING: Figure 2
【課題】弁体主軸の長さを短くすることができ、排水弁装置の高さを低くして、比較的低いシルエットを有する水洗大便器に配置することができる排水弁装置を提供する。【解決手段】排水弁装置２８は、弁体主軸の引上げに応じて排水口を開閉する弁体４８と、小洗浄用フロート機構であって、弁体主軸に係合可能に形成された小洗浄側カム係合部９４と、小洗浄用フロート９６とを備え、小洗浄用フロートの下降により小洗浄側カム係合部と弁体主軸との係合が解除される小洗浄用フロート機構５２と、大洗浄用フロートの下降により大洗浄側カム係合部と弁体主軸との係合が解除される大洗浄用フロート機構５４と、ケーシング部とを有し、弁体主軸７６が、大洗浄モード用の引上げ量を引上げられたときに大洗浄側カム係合部１１４と係合し、小洗浄モード用の引上げ量を引上げられたときに小洗浄側カム係合部９４と係合する１つの共通突起部８０を備えている。【選択図】図２
