。An impeller 2 having a tapered shaft portion at one end and a bolt hole in the center, and a tapered hole having the same taper that closely contacts the outer peripheral surface of the tapered shaft portion of the impeller and having a smaller diameter than the tapered hole. A shaft having a threaded hole into which a bolt is threaded, and the impeller is threaded from the other end of the impeller into the threaded hole of the shaft through the bolt hole, and a gap is created by the centrifugal force while the impeller and shaft are rotating. a tightening bolt taperingly connects the impeller to the shaft with no tightening interference, and the working radius of the joint surface of the end face of the shaft and the impeller, which is the power transmission surface between the impeller and the shaft, is the impeller. An impeller mounting device characterized in that the radius of action of the joint surface of the bolt and the tightening bolt is larger than the radius of action.
