WATER-SAVING MEMBER AND WATER-SAVING TYPE WATER TAP FAUCET

PROBLEM TO BE SOLVED: To facilitate the installing work and provide a water saving effect at low cost by closely fitting a short cylinder having a water hole for limiting the flow rate to the water port of a water tap faucet, and installing a stop collar on the upper end of the cylinder. SOLUTION: A water-saving-member 1 is formed of a cylinder 2 having a water hole 3 and a stop collar 4. The short cylinder 2 is inserted to the water port 6 of a water tap faucet 5 so as to be closely fitted to the inner wall with the stop collar 4 upward. The stop collar 4 has an outer diameter larger than the outer diameter of the cylinder 2 and larger than the inside diameter of the water hole 6. According to such a structure, a feed passage is narrowed by the water hole 3 of the water-saving member 1 when a valve 7 is full opened to limit the outflow quantity from a faucet 8. A spring 9 is installed under the screw shaft 10 of the water tap faucet 5 so as to fill the thread of the screw shaft 10, whereby the opening of the valve 7 is limited to narrow the feed passage.
