PROBLEM TO BE SOLVED: To provide an ejector capable of improving mixing performance of drive flow of gas/liquid two phase condition and suction flow of gas phase refrigerant and adjusting flow rate of refrigerant passing through the ejector by a low cost structure. SOLUTION: This ejector is provided with a gas phase passage member 21 including gas phase refrigerant passage 21a in which gas phase refrigerant flows toward a suction space 24. A fluid passage of high pressure fluid is reduced between an outer circumference tapered shape 21f formed on an outer circumference surface 21e of the gas phase passage member 21 and an inner wall tapered shape 17c of an inner wall part 17b of a main body 17. The gas phase passage member 21 is rotated as one body with a rotor by a stepping motor and rotating force is converted in displacement force in a stream line direction R by screw parts 17a, 21c to displace the gas phase passage member 21.
