Zusammenfassung:PROBLEM TO BE SOLVED: To provide an ejector capable of configuring a center axis of a decompression space, a center axis of a pressure raising space, and a center axis of a valve member so as to be coaxial.SOLUTION: A nozzle forming portion 222 forming a decompression space 220b and a middle body 230 forming a pressure raising space 232 are positioned so as to make a center axis of the decompression space 220b and a center axis of the pressure raising space 232 coaxial, and coupled with each other by a first fastening member 225. The middle body 230 and a base body 27 supporting a shaft 242 of the valve member 240 are positioned so as to make the center axis of the pressure raising space 232 and the center axis of the valve member 240 coaxial and coupled with each other by a second fastening member 274.SELECTED DRAWING: Figure 2 【課題】減圧用空間の中心軸、昇圧用空間の中心軸、弁部材の中心軸それぞれを同軸となるように構成可能なエジェクタを提供する。【解決手段】減圧用空間220bを形成するノズル形成部222と、昇圧用空間232を形成するミドルボデー230とを、減圧用空間220bの中心軸と昇圧用空間232の中心軸とが同軸となるように位置決めした状態で、第1締結部材225により互いに連結する。そして、ミドルボデー230と弁部材240のシャフト242を支持するベースボデー27とを、昇圧用空間232の中心軸と弁部材240の中心軸とが同軸となるように位置決めした状態で、第2締結部材274により互いに連結する。【選択図】図2
