PROBLEM TO BE SOLVED: To sufficiently suppress the deterioration of boosting performance of an ejector displacing a passage forming member.SOLUTION: A passage forming member 35 is disposed on the inside of a body 30 of an ejector 13, and a nozzle passage 13a and a diffuser passage 13c are formed between the body 30 and the passage forming member 35. A plurality of straightening plates 38 for promoting a coolant flow circulating in the diffuser passage 13c are fixed to the passage forming member 35, and an actuation rod 37e transmitting driving force outputted from a drive mechanism 37 to the passage forming member 35 is coupled to a connecting member 39 connecting axial end portions of the plurality of straightening plates 38. Therefore, it is suppressed that the actuation rod 37e obstructs the coolant flow circulating coolant passages formed between the straightening plates.SELECTED DRAWING: Figure 3 |
