DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flushing water discharge device capable of appropriately adjusting the flushing water discharge flow rate to a toilet.

[0002]

2. Description of the Related Art A flush water discharge device for flush toilets is required to perform flushing of toilets as intended by reducing the flow rate of flush water as much as possible (to have a water saving structure). You. This demand has become increasingly strong in recent years when water shortages often occur, and various flushing water discharge devices have been developed. Furthermore, due to the fact that the tap water pressure varies considerably from place to place, it is extremely inconvenient for the conventionally proposed washing water discharge device to accurately adjust the amount of discharged water. This is because, in the case of a conventional flushing water discharge device, the flushing water discharge flow rate is adjusted with respect to the operation amount such as adjusting the lift amount of the valve body or adjusting the relative rotation amount between the orifices arranged in an overlapped manner. By relying on large operations.

[0003]

In view of the above-mentioned circumstances,
The present invention avoids the disadvantages of the conventional water-saving type flush water discharge device,
It is an object of the present invention to provide a washing water discharge device capable of easily and promptly performing fine adjustment of a discharge flow rate.

[0004]
