ーンポンプ。 A pump housing, a cam ring that is housed in the pump housing and has a cam surface having a suction curved section, a large diameter curved section, a discharge curved section, and a small diameter curved section, and a plurality of vanes that are in sliding contact with the cam surface of this cam ring. In the vane pump, the vane pump includes a rotatable rotor held on the circumference, and a side plate that is disposed on the side of the cam ring and has a suction port and a discharge port formed on a surface that faces the cam ring, and the suction curved portion is connected to the suction port. Consisting of a suction part that increases the amount of lift that opens and a decreasing part that decreases the amount of lift that opens, a whisker groove is formed so that the suction port and the vane chamber in which the rear end vane slides in the decreasing part communicate with each other. A vane pump that is characterized by:
