PROBLEM TO BE SOLVED: To prevent fusion due to friction of a rotor and a case while preventing the rotor from being detached from the case.SOLUTION: The pump comprises: a detachable/attachable pump unit having a case and a rotor rotatably supported by the case; a driving unit for rotary-driving the rotor; and a coupling part for coupling a driving shaft of the driving unit and the rotor. The coupling part is configured to convert one part of torque transmitted from the driving shaft into a force in a direction of a rotation axial direction of the coupling part for pushing the rotor toward the case. |
