PROBLEM TO BE SOLVED: To provide a toilet bowl flushing water supply device which is equipped with a float portion for switching between the ejection and stop of water toward a toilet bowl flushing water tank from a water supply valve, along with a vertical motion, in which a sufficient quantity of water is stored in a tub water-storage portion during the ejection of the water from a water supply valve, and which rapidly discharges the water in the tub water-storage portion when the ejection of the water from the water supply valve is stopped. SOLUTION: This toilet bowl flushing water supply device comprises the water supply valve 32 for switching between the ejection and stop of the water from a water supply pipe 31, and the float portion 33 for switching between the ejection and stop of the water from the water supply valve 32, along with the vertical motion. The float portion 33 comprises: the tub water-storage portion 51 which is supplied with the water ejected from the water supply valve 32; an air reservoir portion 52 which is formed in a lower portion and opened downward; a drain outlet which makes the tub water-storage portion 51 and the air reservoir portion 52 communicate with each other; a drain outlet 55 which discharges the water in the tub water-storage portion 51 along an outer surface of the float portion 33; and an air vent hole 56 which makes the air reservoir portion 52 and the outside of the float portion 33 communicate with each other, and which is closed with the water discharged along the outer surface from the drain outlet 55.
