PROBLEM TO BE SOLVED: To provide a structure of superior cost performance in a turbo compressor of a type supporting a shaft on which compression blades are attached by rolling bearing mechanisms arranged at positions separate in an axial direction. SOLUTION: The rolling bearing mechanism consists of one of a deep groove ball bearing 5a, a tapered roller baring 5c or a cylindrical roller bearing 5b in the turbo compressor of the type rotatably supporting the shaft 4 on which the compression blades 4a are attached by the rolling bearing mechanisms 5, 5 arranged at positions separate in the axial direction.
