<P>PROBLEM TO BE SOLVED: To easily adjust delivery water amount. <P>SOLUTION: A water-saving device comprises: a casing 11 of which one end is an attaching opening to a water supply port 3 and other end is a water discharge side opening 13 discharging water flow; a throttle member 21 with a first hole part 24 formed for throttling water flow supplied from the water supply port 3 in the casing 11; and a nozzle member 31 of which one face is a water discharge face 31a facing the water discharge side opening 13 and in which a second hole part 33 communicating with the first hole part 24 is formed at the opposite side of the water discharge face 31a and a plurality of water ejection holes 36 are formed for ejecting water flow from the second hole part 33 through the water discharge face 31a. Either one of the first hole part 24 and the second hole part 33 rotates with respect to the other so that the deviation amount between the first hole part 24 and the second hole part 33 changes, thereby adjusting the amount of water. <P>COPYRIGHT: (C)2012,JPO&INPIT |
