ABSTRACT:
Disclosed is a water saving device which provides the pressure and amount of water to be delivered that can satisfy the comfortable sense of water usage, regardless of whether the water may be supplied under the high pressure or low pressure or whether the water may be supplied in the larger or smaller amount. In accordance with the present invention, the water saving device comprises a hollow cylindrical body that is adapted to be attached to a water passage conduit or pipe. The hollow cylindrical body includes a first plate member disposed perpendicular to the direction of the water flowing through the water passage conduit or pipe. The first plate member has a plurality of first water passage holes formed thereon at regular intervals with regard to each other in the circumferential direction. A water guide member is further included. The water guide member is provided on the location where each of the first water passage holes is formed on the downstream side of the first plate member, and is capable of guiding the water flow in the circumferential direction while it causes the water to flow obliquely and downwardly toward the downstream side through each of the first water passage holes.
