ンポンプ。 A plurality of vanes protruding outward in the radial direction are provided at equal intervals on the outer periphery of the rotor, and the inner space of the cam ring divided by these vanes is defined as a pump chamber, and a side plate is in contact with the side surface of each vane. In the vane pump, fluid is sequentially sucked into each of the pump chambers sealed by a suction port provided on the side plate, and fluid is compressed and discharged sequentially from each pump chamber to a discharge port. A vane pump characterized in that a concave groove is formed on the outer periphery of the opposite side in the circumferential direction and connects the fluid supply port provided in the pump housing and the suction port to form a fluid supply path.
