Abstract
A centrifugal compressor comprises a rotation shaft, an impeller, and a casing. The impeller has a hub and a plurality of blades. The casing has an opposite surface facing a back surface of the hub, and a projection projecting from the opposite surface toward the impeller. The hub is provided with an accommodation space that accommodates the projection. The accommodation space includes a through hole penetrating the hub from the back surface toward an external radial surface. The through hole opens while avoiding the blades.
