<P>PROBLEM TO BE SOLVED: To enable to adjust easily a water ejection direction by limiting a water discharge amount. <P>SOLUTION: A water-saving device comprises a casing 11 mounted on a water supply port 3 of a faucet 2, a throttle component 21 in which a water passing hole 23 throttling a flow of a feed water is provided, a nozzle component 31 in which a plurality of water discharge holes 32 is provided and connected with the water passing hole 23 and of which a surface is combined with the throttle component 21 as a water discharge surface 31a facing with an opening 13 on the water discharge side, and a packing 51 in slidable contact with the throttle component 21 disposed in the casing 11. An exterior surface of an assembly 54 of the throttle component 21 and the nozzle component 31 has a semi-spherical surface and a slidable contact surface of the packing 51 has a spherical seating face. The assembly 54 makes a rolling motion inside of the casing 11. Thus, an angle of the water discharge surface 31a of the nozzle component 31 changes variably. <P>COPYRIGHT: (C)2012,JPO&INPIT |
