プ。 The inner surface is a curved surface that gradually increases in diameter, and the pump body has a suction port on the small diameter side of this curved surface and a discharge port on the large diameter side. The pump has a rotary vane that rotates and a cover that covers the pump body, and has a gap that allows air to flow between the boss portion of the rotary vane connected to the drive shaft of the motor and the cover, and drives the vane. A fluid pump comprising a sound insulating case having an air inlet hole and an overflow hole between the bearing part of the drive motor and the cover.
