Abstract
An ejector has a swirling space, a pressure reducing space, a suction passage, a pressure increasing space, a nozzle passage, a diffuser passage, a passage forming member that forms the nozzle passage and the diffuser passage, and a vibration suppressing portion that suppresses a vibration of the passage forming member. The vibration suppressing portion has (i) a first elastic member that applies a load to the passage forming member in a direction in which an area of a cross section perpendicular to the direction of the central axis of the nozzle passage and the diffuser passage decreases and (ii) a second elastic member that applies a load to the passage forming member in a direction opposite from the direction in which the first elastic member applies the load to the passage forming member.
