Abstract:
A scroll structure of a centrifugal compressor 1 having a spirally formed scroll passage 13. The scroll passage 13 includes: a flat connecting portion A at a flow passage joint 23 where a scroll start and a scroll end of the scroll passage 13 meet, this flat connecting portion having a flat cross-sectional shape with a same height as that of an outlet passage of a diffuser; and a transition part 21 where the flat cross-sectional shape of the flat connecting portion A gradually changes back to a circular cross-sectional shape along a circumferential direction.
