Claims

[Claims for Utility Model Registration] 1. A rotor with vane pumps inserted into a plurality of grooves provided on the outer periphery is attached to the rotating shaft in a casing provided on the protruding side of the rotating shaft of the motor, and a rotor is installed on the rotating shaft of the motor, and a rotor is installed in which vane pumps are inserted into a plurality of grooves provided on the outer periphery, and liquid is sucked into the casing. In the vane pump, the mechanical seal is formed with a fixed member, a rotating member, and one end of which is locked to the rotor, and the other end of the vane pump is configured to form a mechanical seal between the rotor and the motor. A vane pump characterized by comprising a spring that presses a member. 2. The vane pump according to claim 1, wherein the casing is formed integrally with the motor. 3. Utility model registration claim 1, characterized in that the spring is fitted into a boss formed on the rotor, and one end is engaged with a notch provided on the outer periphery of the boss. Or the vane pump described in paragraph 2. , 4. A utility model characterized in that the spring has an outer circumferential groove formed in a boss formed on the rotor, is fitted into the outer circumferential groove, and has one end locked in a notch provided in the outer circumferential groove. A vane pump according to registered claim 1 or 2.
