Abstract
A connection passage is formed by a first impeller housing member, a motor housing member, and a second impeller housing member. This prevents, for example, the formation of a gap between a housing and a pipe, which is separate from the housing, in a centrifugal compressor like in a configuration in which a first discharge port and a second suction port are connected to each other by attaching the pipe to the housing. The connection passage is formed only by sequentially overlapping and coupling the first impeller housing member, the motor housing member, and the second impeller housing member with each other in an axial direction of the rotary shaft. This eliminates, for example, the need to provide a structure in the pipe that absorbs the dimensional tolerances that occur between the housing and the pipe when attaching the pipe to the housing.
