<p>Provided is a water-saving piece capable of vertical direction movement and other reciprocal movement of internal members, with high precision, by external operation with the water-saving piece remaining mounted to the water faucet. The water-saving piece comprises: a water flow forming section (110) provided internally with a gap that serves as a flow path for water, and from which accelerated water flow is pushed out from the gap to a downstream side; a case (120) that pours out accelerated water flow pushed out from the water flow forming section (110); a movable mechanism (130) that reciprocally moves a first member (10) wherein the case (120) is disposed and a second member (20), the water-saving piece comprising at least both said members; and a guide section (140) disposed in the second member (20) and which moves along an outer peripheral wall surface (25) of the case (120). The direction for reciprocal movement of the first member (10) and the second member (20) by the movable mechanism (130) is parallel to the direction of the case (120) shaft and the movement direction is aided by the guide section (140) to easily be parallel to the case (120) shaft.</p> |
