A centrifugal pump used for assisted circulation or extracorporeal circulation which comprises: a housing having an inlet for a liquid and an outlet for a liquid； a rotating body which is disposed inside the housing, comprises a rotating shaft and transfers the liquid from the inlet to the outlet and sends out the liquid from the outlet by the rotation of the rotating shaft； and a bearing which is disposed on the housing and journals the rotating shaft. In this centrifugal pump, an elastic member is disposed between each bearing and the housing. The elastic member stretches when the bearing moves to the rotating body side and shrinks when the bearing moves to the opposite side from the rotating body.
