    • A constant flowrate water saving valve is applicable to a fluid discharge part such as a shower head and discharges a sucked-air mixed water, which presents a feeling of large flow, in a water saving state even when a city water tap is fully opened. A constant flowrate water saving valve comprises a valve body (2) having a peripheral wall (5) formed with a conical-shaped valve seat surface (4), which is varied in diameter from an inner diameter r1 to an inner diameter r2 (r1 > r2), a fluid inlet opening (6) on a side of the inner diameter r1, a vent flow opening (7) on a side of the inner diameter r2 and a plurality of fluid radiant outflow openings (9) extending, while intersecting in an axial direction with predetermined angular spacings, along the peripheral wall, and a movable valve disc (3) received in the valve body to be movable in the axial direction, the valve being such that when the movable valve disc is fully seated on the conical-shaped valve seat surface in the valve body, a fluid inlet opening side portion of the valve body communicates with an outside through respective upper edge side opening portions (9A) of the plurality of fluid radiant outflow openings and a vent flow opening side portion of the valve body communicates with an outside through respective lower edge side opening portions (9B) of the plurality of fluid radiant outflow openings, and a shower head uses the constant flowrate water saving valve.

    • PROBLEM TO BE SOLVED: To provide a shower head which ensures the force of a flow velocity having a use feeling as a shower and generating a large amount of negative ions when the shower is used. SOLUTION: A negative ion generation means is provided to a shower head main body 2 on the side of the fluid outflow part thereof. This negative ion generation means comprises a fluid flow channel control member 3 equipped with a fluid discharge port 7 setting the flow direction of a fluid in a radial direction with respect to the flow direction of the fluid on the side of the fluid outflow part of the shower main body 2 and a fluid discharge port forming member 4 equipped with the inner peripheral wall 18 opposed to the periphery of the fluid discharge port of the fluid flow channel control member so as to provide a peripheral gap G. The inner peripheral wall of the fluid flow channel control member is formed by an irregular reflection surface 19 for irregularly reflecting the fluid discharged from the fluid discharge port of the fluid flow channel control member and negative ions are generated by the irregular reflection discharge of the fluid.
