PROBLEM TO BE SOLVED: To provide a fluid pump for keeping bearings in a well lubricated condition while suppressing the occurrence of vibration. SOLUTION: A cylindrical rotor 11 having an impeller 6 is supported to be rotatable relative to a fixed shaft 5 via a plurality of bearings 14 which are spaced from each other in the direction of the axial center of the fixed shaft 5 while covering the periphery of the fixed shaft 5. Among the plurality of bearings 14 between the rotor 11 and the fixed shaft 5, a flow space 16 is provided where fluid can flow. Herein, there are provided a communication hole 17 for communicating the flow space 16 with the outer periphery of the rotor 11 and a flow accelerating means 18 for accelerating the flow of fluid through the communication hole 17 between the flow space 16 and the outer periphery of the rotor 11.
