Abstract

A centrifugal pump () includes a housing (), an impeller () that is rotatably disposed in the housing (), a shaft () that is provided at a center rotational axis of the impeller (), and bearings members () that respectively and pivotally support the shaft ends (). An elastic body () which is elastically deformable at least in an axial direction of the shaft () is provided between at least one of the bearings () and the housing () or at an intermediate portion of the shaft () in the axial direction. A tightening load exerted on the shaft and bearing members can be maintained in a predetermined range even when age-related deformation of the housing or other components occurs.
