The objective of the present invention is to prevent mechanical loss caused by thermal expansion and rotational oscillation of a rotary shaft in a turbo compressor that compresses a low-pressure refrigerant used at a maximum pressure of less than 0.2 MPaG, thereby increasing the efficiency of a turbo refrigeration device. This turbo compressor, which compresses a low-pressure refrigerant used at amaximum pressure of less than 0.2 MPaG, is equipped with: a rotary shaft (25); an electric motor (13) that is provided coaxially on the middle portion of the rotary shaft (25), and that rotationallydrives the rotary shaft (25); impellers (23a and 23b) affixed to one end of the rotary shaft (25) and constituting a compression unit (23); a first bearing (27) pivotally supporting the rotary shaft (25) between the electric motor (13) and the impellers (23a and 23b); and a second bearing (28) pivotally supporting the other end of the rotary shaft (25). The first bearing (27) is a rolling bearing,and the second bearing (28) is a sliding bearing.
