A pump housing, a cam ring that is eccentrically housed in the pump housing and has a concave groove on one side that houses the friction ring, and a plurality of vanes that slide in sliding contact with the inner circumferential surface of the cam ring and can slide radially. It consists of a housed rotor, the cam ring and side plates arranged on both sides of the rotor and forming a suction port and a discharge port, and sucks working fluid from the suction port into a pump chamber formed between each vane, A variable valve that compresses and discharges to the discharge port, applies this discharge pressure to a half part between the walls of the cam ring and the housing, and moves the cam ring from an eccentric position to a position concentric with the rotor to adjust the discharge flow rate. In the capacity type vane pump, a dividing groove is provided by dividing the concave groove provided with the friction ring at a position corresponding to the discharge port, a divided friction ring provided in the dividing groove, and a discharge in the dividing groove. A variable displacement vane pump characterized by being equipped with a balance groove for introducing pressure.
