タンデムポンプ。 A first cam ring, an intermediate side plate, a second cam ring, and a rear side plate are stacked and inserted in this order into the pump housing, and a vane is provided in the first cam ring and the second cam ring that slides into inner circumferential cam surfaces formed in these cam rings. In the tandem pump, a first rotor and a second rotor each of which is slidably held in a radial direction are fitted therein, and a discharge port and a suction port are formed in the side plate and the rear side plate. A tandem pump characterized in that a screw hole into which a removal tool is screwed is formed on the surface that contacts the rotor.
