<p>[PROBLEMS] A water-saving device capable of realizing a discharge pressure and a discharge amount that provide a user with excellent feeling of use irrespective of the level of water pressure and the amount of water supply on the supply side and also capable of reducing the amount of use of water per unit time. [MEANS FOR SOLVING THE PROBLEMS] The water-saving device has a hollow cylindrical body and is connected to a water pipe. A first plate body and a second plate body are disposed in the hollow cylindrical body so as to be parallel to each other and perpendicular to the direction of flow of clean water flowing in the water pipe. A first containing chamber is formed by the first and second plate bodies and by an inner peripheral wall formed between the first plate body and the second plate body. The inner peripheral wall has an inner diameter gradually decreasing toward that portion of the hollow cylindrical body at which the second plate body is placed. The first plate body has first water holes located at predetermined circumferential intervals. The first plate body further has guide members formed on that wall of the first plate body which is on the first storage chamber-side, with the guide members located at positions where the first water holes are formed. The guide members cause flows of the clean water, flowing into the first containing chamber through the first water holes, to run obliquely downward and guide the clean water in the same circumferential direction.</p> |
