ABSTRACT:
Within an angular area where each vane of a vane pump having backpressure grooves is moved radially inwardly as the rotor rotates, the outer circumferential edge of the backpressure groove is indented toward the rotational axis of the rotor along a locus drawn by the radial innermost end of each vane so that the radial innermost end of each vane does not protrude radially inwardly beyond a predetermined distance from the indented part of the outer circumferential edge of the backpressure groove.
