Abstract

See full text

The present invention provides a flush water tank device (4), including: a flush water tank (10); a discharge valve (12) that causes the lower spout port to eject the flush water by switching between discharge and stopping of the flush water; a water pressure driving mechanism (14) that drives the discharge valve with a water supply pressure; a first on-off valve (19) that switches between water ejection and stopping of the flush water; a second on-off valve (18) that switches between water supply and stopping of the flush water to the water pressure driving mechanism; and a delay valve opening mechanism (21) that causes the second on-off valve to open with a delay of predetermined time after water ejection from the upper spout port is started, using a part of the flush water introduced via the first on-off valve, to supply the flush water to the water pressure driving mechanism.
