Abstract
A flush water volume regulator is provided, capable of constraining the occurrence of a buoyancy force acting on a water reservoir, whereby flush water in the water reservoir can be circulated with flush water in a flush water tank outside the water reservoir. The flush water volume regulator 38 of the invention has a water reservoir, being a water reservoir 40 disposed inside this flush water tank 16, capable of storing a predetermined amount of flush water, on which an opening 40a through which flush water within water reservoir 40 and flush water outside water reservoir 40 can pass, and an opening-closing valve 42 for opening 40a during the standby state before starting a flush and for blocking opening 40a or reducing the opening surface area of opening 40a when the water level inside flush water tank 16 is dropping after starting a flush.
