In the forward/reverse rotary variable displacement vane pump, the movable ring is displaced along the side plate in response to the change in the amount of eccentricity between the movable ring and the rotor, and the discharge amount is increased or decreased. A variable displacement vane pump of forward and reverse rotation type, in which a port communicating with an intake port of the vane pump or a tank opened to the atmosphere is provided on the side plate in the vane chamber confinement region on the side transitioning from the suction side to the discharge side.
