<p>A water-spraying nozzle (1) equipped with a main nozzle body (6) in the interior of which a flow path (10) for water is formed, an operating lever (15) attached to the main nozzle body (6) so as to be able to move closer or farther away, an on/off valve (13) for opening/closing the flow path (10), and a relay lever (16) that is rotatably supported on the main nozzle body (6) and has a fulcrum section (17), force point sections (18, 19) abutting against the operating lever (15), and an action point section (20) abutting against the on/off valve (13), the relay lever (16) rotating to open/close the on/off valve (13) in accordance with the positional relationship between the operating lever (15) and the main nozzle body (6), wherein: two or more of the force point sections (18, 19) of mutually different distances from the fulcrum section (17) are provided to the relay lever (16); at a stop-water position of the on/off valve (13), the force point section (18) formed farthest from the fulcrum section (17) is made to abut against the operating lever (15); and at a position of the on/off valve (13) where the opening degree becomes greater than a predetermined degree, the other force point section (19) is made to abut against the operating lever (15). This configuration makes it possible within a water-spraying nozzle to reduce the working load on the operating lever even in a high-water-pressure state of the stop-water position.</p> |
