摘要： It is intended to provide a centrifugal compressor equipped with a resin housing which does not compression efficiency without offsetting merits such as weight saving and cost reduction. A centrifugal compressor 10 includes a resin housing 20 formed by a volute section 20a and a path forming section 20b. An impeller 14 fixed to a rotating shaft 12 in a center of the path forming section 20b. An annular shroud 22 is arranged in a depression 20b 2 carved in an inner wall 20b 1 of the path forming section 20b. The annular shroud 22 forms an outer wall of a flow path c for a gas to be compressed and an outer wall of a diffuser d (static-pressure increasing region). A downstream end of the annular shroud 22 is fixed via a spacer 24 to a wall 32 by a bolt 6. The wall 32 constitutes a part of a bearing housing 30. Even when the resin housing 20 thermally deforms, a clearance T between the annular shroud 22 and a curved profile 16a of the blade 16 can be kept at a set dimension.
