PROBLEM TO BE SOLVED: To prevent washing water present in a wash water tank from infiltrating into a drive part through an operation member.SOLUTION: The flush toilet bowl device according to an embodiment comprises a toilet bowl body, a wash water tank, a drain valve device, and a drive unit. The wash water tank stores wash water to be fed to the toilet bowl body. The drain valve device comprises a drain valve disposed in the wash water tank to open or close an exhaust port of the wash water tank by moving upward or downward. The drive unit drives the drain valve of the drain valve device. The drive unit comprises a drive part, a slender drain valve side operation member, a slender drive part side operation member, and a connecting part. The drive part is driven by electricity. One end part of the drain valve side operation member is connected to the drain valve. One end part of the drive side operation member is connected to the drive part. The connecting part connects the drain valve side operation member and the drive part side operation member, with the other end parts of the drain valve side operation member and the drive part side operation member kept in a state of being mutually apart.SELECTED DRAWING: Figure 4

【課題】洗浄水タンク内の洗浄水が操作部材を伝って駆動部へ浸入することを防止すること。【解決手段】実施形態に係る水洗大便器装置は、便器本体部と、洗浄水タンクと、排水弁装置と、駆動ユニットとを備える。洗浄水タンクは、便器本体部に供給する洗浄水を貯留する。排水弁装置は、洗浄水タンク内に配置され、上下動することにより洗浄水タンクの排水口を開閉する排水弁を備える。駆動ユニットは、排水弁装置が備える排水弁を駆動する。また、駆動ユニットは、駆動部と、細長状の排水弁側操作部材と、細長状の駆動部側操作部材と、接続部とを備える。駆動部は、電力により作動する。排水弁側操作部材は、排水弁に一端部が接続される。駆動部側操作部材は、駆動部に一端部が接続される。接続部は、排水弁側操作部材および駆動部側操作部材の他端部同士を離した状態で、排水弁側操作部材と駆動部側操作部材とを接続する。【選択図】図４
