1. TECHNICAL FIELD OF THE INVENTION;Water supply side of toilet bowl;2. The technical problem the invention is trying to solve;If the water pressure is weak, the water washing efficiency is lowered, if the water pressure is strong water supply is higher than the reference value, and also to solve the problem that the water is consumed unnecessarily because it is not controlled even if the water leaks due to a failure in the water supply side.;3. Summary of solution of design;It is composed of a cylindrical body of the ordinary light lower strait and is provided with a body 21 in which the water supply passage 22 is communicated at right angles to the rear and the lower part thereof, and a valve body 27 is embedded therein, and a valve body 27 is embedded therein. The upper part of the body 21 is covered by the cap 23, the inlet pipe 24 is communicated to the rear of the water supply passage 22, which is an opening and closing valve 28 for blocking the water supply passage 22 is configured In the water side 20, the control knob (29) to grip the upper portion of the on-off valve 28 with the user's hand, to selectively adjust the water supply while rotating in the forward and reverse directions, and to completely close the on-off valve (28) (29) It is to solve the problem characterized in that the configuration.;4. Important uses of the devise;Water saving device of water supply side
