Abstract
The present invention provides a toilet bowl flushing water tank device which can largely open a discharge valve element instantaneously and, at the same time, can ensure a relatively large space in the vicinity of a discharge valve device thus enhancing a discharge capacity with a small power. A push button mounted on a tank lid body of a flushing water tank body is arranged at a position offset to one side from a position where a discharge opening is formed, a leverage device is constituted of a lever which is interlockingly connected to the discharge valve element and a pedestal which pivotally supports a middle portion of the lever. The pedestal pivotally supports a middle portion of the lever at a position closer to a push button side than the discharge valve device.
