Zusammenfassung:	To provide a fluid injection pipe capable of adjusting an air flow and air velocity of a discharge jet flow without causing loss of the discharge jet flow.SOLUTION: A fluid inject pipe 11 includes: an injection pipe main body 14 that includes a fluid outlet 14a at a front end; a restriction member 15 that is disposed at the fluid outlet 14a; and an operation portion 16 that controls the restriction member 15. The restriction member 15 includes an outlet opening 17 that is opened only to the front of the fluid injection pipe 11. An area of the outlet opening 17 changes concentrically as the operation portion 16 is driven.SELECTED DRAWING: Figure 2 【課題】吐出噴流の損失を生じることなく吐出噴流の風量及び風速を調整し得る流体噴管を提供する。【解決手段】流体噴管１１は、前端に流体出口１４ａを有する噴管本体１４と、前記流体出口１４ａに配設される絞り部材１５と、該絞り部材１５を制御するための操作部１６と、を備える。前記絞り部材１５は、流体噴管１１の前方へのみ開口する出口開口１７を有する。この出口開口１７の面積は、前記操作部１６が駆動されることにより同心的に変化する。【選択図】図２
