Beschreibung
Zusammenfassung:	In a centrifugal compressor, when the position of the tongue of the scroll section in the circumferential direction of the impeller is defined as 60° and the downstream direction in the rotation direction of the impeller is defined as the positive direction of the position in the circumferential direction, a diffuser section outer diameter distribution indicating a relationship between the position in the circumferential direction and outer diameter R of the diffuser section includes an outer diameter increasing portion where the outer diameter R increases going toward the positive direction, and in the diffuser section outer diameter distribution, the position of a start point of the outer diameter increasing portion is 150° or less, and the position of an end point of the outer diameter increasing portion is 270° or more.
