Abstract

PURPOSE:To provide a proper clerance between the inner surface of a housing and an impeller through work of high accuracy only on a pump portion by providing a joint for transmitting the rotation of a motor shaft to the impeller between a pump and the motor shaft. CONSTITUTION:An impeller shaft 74 of a pump 14 is provided independently of a shaft 40 of a motor 12, and a joint 76 for transmitting the rotation of the motor shaft 40 to an impeller 54 while allowing for axial movement of the impeller 54 is applied between the pump 14 and motor 12. Thus, a work with high accuracy only on the pump portion 14 can maintain proper side clearance and radial clearance between the inner surface of a pump housing 52 and impeller 54 which are requirements for exhibiting high performance of the pump.
