摘要: A centrifugal compressor (1) that includes: an auxiliary bearing (7) which supports a shaft (2), which is supported by a magnetic bearing (6), when the shaft (2) is displaced from a reference position; and a stopper (8) that is provided only for a first auxiliary bearing (7a) among the first auxiliary bearing (7a) and a second auxiliary bearing (7b), that is fixed to the shaft (2), and that restricts a movement of the shaft (2) in both directions in an axial direction by the stopper (8) being brought into contact with the first auxiliary bearing (7a).
