摘要： A variable displacement vane pump includes: a rotor to be rotatively driven; a plurality of vanes slidably housed in the rotor; a cam ring allowed of eccentric with respect to a center of the rotor, the cam ring having an inner circumferential cam surface in sliding contact with a distal end portion of the vane; a pump chamber defined by the adjacent vanes, the rotor, and the cam ring; a suction port to guide hydraulic fluid to be suctioned to the pump chamber; and a discharge port to guide hydraulic fluid to be discharged from the pump chamber. An outer circumference of an opening portion of the suction port is formed so as to be positioned along the inner circumferential cam surface of the cam ring or at an outside of the inner circumferential cam surface regardless of eccentricity of the cam ring with respect to the rotor.
