ベーンポンプ。 A pump housing in which a suction chamber and a discharge chamber are formed, a cam ring that is disposed inside the pump housing and whose inner peripheral surface is a cam surface, a rotor that is attached to a rotating shaft and can freely rotate within the cam ring, and a radius of the rotor. The vane is fitted into each of a plurality of slits formed in the direction so as to be slidable in the radial direction, and the wire end edge is in contact with the cam surface.The bottom of each slit has a back that communicates with the discharge chamber. A vane pump in which a pressure chamber is molded and the inner end surface of the vane facing the back pressure chamber is an inclined surface facing in the rotational direction of the rotor.
