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 port is provided in the side plate in the vane chamber confinement region on the side transitioning from the suction side to the discharge side, and the port is opened to the atmosphere through a check valve that allows outflow from the port and prevents backflow. Or a forward/reverse rotary variable displacement vane pump connected to the suction port of the vane pump.
