PROBLEM TO BE SOLVED: To provide a sprinkling nozzle with excellent operability.SOLUTION: A sprinkling nozzle 100 includes: a first flow channel WR1 having a negative pressure generating part NP1 whose cross sectional area increases in the middle a first discharge hole H1 which is connected to a terminal of the first flow channel WR1 a second flow channel WR2 which is branched from the negative pressure generation part NP1 and extends to a downstream side a second discharge hole H2 which is connected to a terminal of the second flow channel WR2 and an opening/closing valve VL1 which can open and close the first flow channel WR1 on a downstream side than the negative pressure generating part NP1. The sprinkling nozzle 100 can make a packing unnecessary at a branch point of a water channel.SELECTED DRAWING: Figure 7COPYRIGHT: (C)2018,JPO&INPIT【課題】操作性に優れた散水ノズルの提供。【解決手段】散水ノズル100は、断面積が途中で拡大している負圧発生部NP1を有する第1流路WR1と、第1流路WR1の終端に繋がる第1吐出孔H1と、負圧発生部NP1から分岐して下流側に延びる第2流路WR2と、第2流路WR2の終端に繋がる第2吐出孔H2と、負圧発生部NP1よりも下流側において第1流路WR1を開閉しうる開閉弁VL1と、を有する。この散水ノズル100では、水路の分岐地点でパッキンが不要されうる。【選択図】図7
