Abstract
The present invention provides a flush water tank device () that supplies flush water to an upper and lower spout port of a flush toilet () including; a flush water tank (); a discharge valve (); a first on-off valve () that performs switching between ejection and stopping of the flush water from the upper spout port; a first on-off valve driving mechanism () that is moved from a stopped position to an ejection position based on an user operation; a biasing mechanism () that causes the first on-off valve driving mechanism to move to the stopped position; a holding mechanism () that holds, at the ejection position, the first on-off valve driving mechanism at the ejection position against the bias force; and a releasing mechanism () that releases the holding of the first on-off valve driving mechanism, using the flush water flowing out from the first on-off valve.
