特徴とするベーンポンプ。 A pump housing, a cam ring housed in the pump housing, a pair of side plates arranged on both sides of the cam ring and having a pair of suction ports and a discharge port formed in opposing positions, and rotatably housed in the cam ring. In the vane pump, the vane is provided with a rotor and a vane that slides on the circumference of the rotor and partitions a pump chamber into a plurality of parts by slidingly contacting the inner circumferential surface of the cam ring, the side surface of at least one of the side plates being sealed with the rotor. A circumferential groove is formed in the portion, and an inclined groove is formed on the side plate in the pump chamber between the suction port and the discharge port that transitions from the expansion process to the compression process by gradually inclining in the rotational direction from the outer periphery. A vane pump characterized in that the inclined groove is formed so as to be in communication with the vane and to protrude when the vane overlaps with the vane.
