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.
