PURPOSE: An impeller integrated driving shaft is provided to eliminate inconvenience in installation and assembly of driving shaft and impeller, while improving production speed in case of mass production of compressor. CONSTITUTION: An impeller integrated driving shaft comprises a driving shaft(31) rotating by the rotating force transmitted by the applied power; a bearing plate(32) arranged at the outer periphery of the driving shaft, and which supports loading of the driving shaft; a radial bearing(33) installed at the contact surface between the inner periphery of the bearing plate and the outer periphery of the driving shaft, so as to suppress frictional force generated during the rotation of the driving shaft; and an impeller(34) installed at an end of the driving shaft, and which has an outer diameter(D2) equal as or smaller than an outer diameter(D1) of the driving shaft, to thereby permit the impeller to be easily and freely inserted through the bearing plate.
