PROBLEM TO BE SOLVED: To provide a toilet bowl flushing water tank device which is formed of: a water storage tank for storing therein flushing water to be fed into a flush toilet bowl; a drain valve formed in a bottom of the water storage tank, for opening/closing a feed passage of the flushing water; a float floating in the water storage tank at a location that is spaced a predetermined distance away from the drain valve; and a connection member connecting between the float and the drain valve, wherein the toilet bowl flushing water tank device ensures the performance of the flush toilet bowl, and facilitates change of a discharge mount of the flushing water from the water storage tank. SOLUTION: In the toilet bowl flushing water tank device, the connection member connecting between the float and the drain valve has upper and lower limiting members mounted thereon at locations that are spaced by a predetermined vertical distance away from each other, and the float is movable in a range defined by the locations at which the upper and lower limiting members are mounted. Further the connection member has a stopper member detachably attached thereto, which prevents the float from lowering when the float is close to the upper limiting member, and prevents the float from elevating when the float is close to the lower inhibiting member.
