Abstract
The present invention provides a water spouting device which enables air bubble entrained water with an increased entrainment rate of air bubbles to be discharged at a low flow rate stage even though the user adjusts the flow rate based on the same feeling as that for a conventional water spouting device, the present water spouting device further enabling, at a high flow rate stage, prevention of discharge of air bubble entrained water with such a total amount as makes the user feel that the resultant amount of water significantly exceeds that intended by the user. A spout cap BC serving as the present water spouting device includes a pressure reducing portionserving as an entrainment rate adjusting portion to adjust the entrainment rate of air bubbles entrained in air bubble entrained water in an air bubble entraining portion. The pressure reducing portionserving as the entrainment rate adjusting portion increases the entrainment rate until inflow water from an inflow portreaches a predetermined flow rate, and suppresses an increase in entrainment rate when the inflow water from the inflow portexceeds the predetermined flow rate.
