Abstract

A centrifugal compressor includes: a compressor impeller; a motor including a stator and a rotor; and a housing. The rotor includes a tubular member, a magnetic body, a first shaft member and a second shaft member, an axial passage, and a plurality of radial passages. A dimension of each of the radial passages in a circumferential direction of the second shaft member gradually increases toward a radially outward side of the second shaft member. Each of the radial passages includes an opening that is opened at the outer peripheral surface of the second shaft member. The outer peripheral surface of the second shaft member has an interposed surface that is interposed between the opening of one of the radial passages and the opening of another of the radial passages adjacent to each other in the circumferential direction of the second shaft member.
