Summary:To provide a washing water tank device in which the occurrence of turbulence of flow at a flow channel branch portion of a water supply device can be suppressed, and a flush toilet bowl device comprising the washing water tank device.SOLUTION: A washing water tank device comprises: a drain valve hydraulic drive unit 14 driving a drain valve using water supply pressure of washing water; and a water supply device 16 which supplies washing water from a water supply source, and comprises a flow channel branch portion 33 for making a flow channel branch toward a flush toilet bowl side flow channel 25 and a drain valve hydraulic drive unit side flow channel 23. The flow channel branch portion of the water supply device comprises: a pre-branch flow channel 33a; a first branch flow channel 33b connected to the flush toilet bowl side flow channel; and a second branch flow channel 33c connected to the drain valve hydraulic drive unit side flow channel. The water supply device further comprises: a first pressure valve 38 which is provided in the first branch flow channel and adjusts pressure of washing water in the first branch flow channel; and a second pressure valve 40 which is provided in the second branch flow channel and adjusts pressure of washing water in the second branch flow channel.SELECTED DRAWING: Figure 8 【課題】給水装置の流路分岐部において流動の乱れを生じさせることを抑制できる洗浄水タンク装置、及びそれを備えた水洗便器装置を提供する。【解決手段】本発明の洗浄水タンク装置は、洗浄水の給水圧を利用して、排水弁を駆動する排水弁水圧駆動部１４と、給水源からの洗浄水を給水する給水装置であって、水洗便器側流路２５と、排水弁水圧駆動部側流路２３とに向けて流路を分岐させる流路分岐部３３を備える、給水装置１６とを備え、給水装置の流路分岐部は、分岐前流路３３ａと、水洗便器側流路に接続される第１分岐流路３３ｂと、排水弁水圧駆動部側流路に接続される第２分岐流路３３ｃとを備え、給水装置は、さらに、第１分岐流路に設けられると共に第１分岐流路内の洗浄水の圧力を調整する第１圧力弁３８と、第２分岐流路に設けられると共に第２分岐流路内の洗浄水の圧力を調整する第２圧力弁４０とを備える。【選択図】図８
