A toilet flush water supply device for supplying flush water to a flush water tank of a flush toilet is disclosed. The toilet flush water supply device comprises a water supply pipe connected to an external water supply source, a water supply valve for switching between spouting and stopping of flush water supplied from the water supply pipe into the flush water tank, a float for switching between the spouting and stopping of the above water supply valve by a vertical movement thereof linked to fluctuations in the flush water level within the flush water tank, and a float guide disposed on the outer surface of the water supply pipe for guiding the vertical motion of the float.

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.

A damper device includes a check valve operated to apply braking force to a rotary shaft having wing portions when rotated in a cylinder in one direction and, when the rotary shaft is rotated in the opposite direction, the check valve is not operated. Movement restricting flow passages for restricting the movement of a viscous fluid between front and rear-side oil chambers divided by the wing portions are formed between an inner wall of the cylinder and the wing portions, and a selective communication passage having the check valve is formed between the wing portions and one of two side walls forming the oil chambers, such that the side wall and the check valve can be rotated along with the rotation of the wing portions, thereby avoiding rotation of the check valve in contact with the inner wall of the cylinder, for pronged service life of the damper device.
