PROBLEM TO BE SOLVED: To provide an emitter and a tube for drip irrigation having the emitter which are capable of stabilizing a discharge amount of irrigation liquid, and further reduction of a cost related to manufacturing.SOLUTION: An emitter 120 has a water intake amount adjusting part for preventing inflow of low-pressure liquid in a water intake part thereof. The water intake amount adjusting part has valve bodies 214 and a fixing part 215. When pressure of liquid which should be flown into the emitter 120 is less than a set value, the valve bodies 214 do not move together with the fixing part 215 and prevent inflow of the liquid to the emitter 120. When the pressure of the liquid is the set value or more, the valve bodies 214 bend toward a downstream side to open a flow channel of the liquid.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2016,JPO&INPIT【課題】灌漑用液体の吐出量を安定化することが可能であり、さらに、製造に係るコストのさらなる削減が可能なエミッタ、および、当該エミッタを有する点滴灌漑用チューブを提供する。【解決手段】エミッタ120は、その取水部に、低圧の液体の流入を防止するための取水量調整部を有する。当該取水量調整部は、弁体214および固定部215を有する。エミッタ120に流入すべき液体の圧力が設定値未満のときは、弁体214は固定部215とともに動かず、当該液体のエミッタ120への流入を防止する。当該液体の圧力が設定値以上のときは、弁体214は下流側に撓んで当該液体の流路を開く。【選択図】図5
