PURPOSE: A structure for coupling a bearing member of a turbo compressor is provided to improve the productivity by reducing the time required for manufacturing a casing. CONSTITUTION: A structure for coupling a bearing member of a turbo compressor includes a casing100 having a predetermined volume, an axial driving motor(20) mounted within the casing for generating a driving force, a driving shaft(30) coupled with a movable element for rotating and transmitting the driving force, first and second impellers mounted at both end parts of the driving shaft for compressing refrigerant gas by stages with rotating within each compressing chamber, and first and second bearing members(210,220) outwardly installed in both parts of the driving shaft for being fixed in the casing to support the driving shaft in a radial direction and a thrust direction, wherein a stepped pulley part is formed at both side surfaces of the casing by protruding the part contacted with the bearing member and a bearing contacting surface of the stepped pulley part is precisely processed for coupling the bearing member.
