Abstract: The present invention is a flush water tank device including a flush water tank main body, a water supply valve, and a discharge valve, in which during a flush of the flush toilet, the discharge valve is opened until a water level in the flush water tank main body is lowered from a predetermined full water level to a predetermined dead water level, a lowering speed of the water level in the flush water tank main body changes at a predetermined inflection water level between the full water level and the dead water level, and the lowering speed of the water level between the inflection water level and the dead water level is faster than the lowering speed of the water level between the full water level and the inflection water level.

Abstract: A discharge valve device includes a valve body, an actuation shaft, a water storage cylinder, and a float, and from when the valve body opens to when the valve body closes, either flushing mode of a large flushing mode in which the flush water in a water storage tank is supplied from a discharge opening to the flush toilet in a first flush water amount or a small flushing mode in which the flush water is supplied in a second flush water amount smaller than the first flush water amount is selectively executable, and the water storage cylinder or the float is configured to change a lowering speed of the float with decrease in water level in the water storage cylinder depending on the selected large flushing mode or small flushing mode.

Abstract: A flush water supply device includes: a water supply valve for switching between a water supplying state and a water stopping state with respect of an inside of the flush water tank; a refill water system on a downstream side of the water supply valve and adapted to allow flush water to be supplied to the flush water tank, and further supplied to a toilet main body as refill water, wherein the refill water system includes a common passage-forming portion which forms a common passage having: an inlet port for allowing inflow of the flush water therethrough; a tank-side outlet port for allowing the flush water to flow out toward the flush water tank therethrough; a main unit-side outlet port for allowing the flush water to flow out toward the toilet main body therethrough; and a vent port; and a vacuum break valve in the common passage-forming portion.
