徴とする、ベーンポンプ。a housing; a rotor housed within the housing and rotated relative to the housing by a rotating shaft;
The rotor includes a number of vanes attached to the outer peripheral surface of the rotor and in sliding contact with the inner peripheral surface of the housing, and a plurality of pump chambers formed by being surrounded by the loader, the housing, and the vanes. A pair of suction and discharge ports for sucking and discharging hydraulic oil are formed in each of the pump chambers, and a pair of suction and discharge ports for sucking and discharging hydraulic fluid are formed in the axial sliding portion between the rotor and the housing, and the suction and discharge ports are formed in the axial sliding portion between the rotor and the housing when the rotor and the housing rotate relative to each other. A vane pump characterized by having a hydraulic chamber connected to the discharge side of a discharge port, and a sliding surface whose side clearance decreases as it moves away from the inside or outside of the hydraulic chamber in the radial direction.
