を与えたことを特徴とするベーンポンプ。 A drive shaft is supported by a body having an internal chamber with one end facing the internal chamber, and the outer surface of a plurality of vanes inserted radially into the rotor provided at the one end can slide against the inner surface of the cam ring. At the same time, both sides of the vane are covered with a pair of side plates forming a suction port or a discharge port for the working fluid,
In a vane pump in which one side plate is biased against the pane by a spring, the one side plate is supported on the body so as to be movable in the direction of the rotational axis of the drive shaft, and the one side plate is attached to the inner surface of the cam ring. A vane pump characterized in that the vane has a tapered shape that expands toward the side plate, and an outer surface of the vane has a shape that matches the tapered shape.
