ポンプ。 A rotor is rotatably disposed inside the cam ring, slits are formed in the rotor in the radial direction at a plurality of angular positions, back pressure chambers are formed inside the radius of the slits, and vanes are slid in the radial direction in each slit. One end of the vane is movably inserted and brought into contact with the inner circumferential cam surface of the cam ring, and oil is discharged by moving the vane as the rotor rotates, and the pressure of the discharged oil is transferred to the back pressure chamber. In the vane pump, the vane is pressed against the inner circumferential cam surface of the cam ring by guiding the vane to the inner peripheral cam surface of the cam ring. A vane pump characterized by inserting a spring that presses against the inner cam surface.
