Claims

[Claims for Utility Model Registration] A housing having an oil suction passage and an oil discharge passage, a ring disposed within the housing, and an inner circumferential surface of the ring and an opposing surface of the housing sandwiching the ring from both sides. A rotor disposed in a space defined by two inner wall surfaces and driven to rotate about an axis eccentric to the center line of the ring; a plurality of vanes that are slidably fitted into radial vane storage grooves formed on the ring, and whose radial outer ends are in sliding contact with the inner circumferential surface of the ring; A vane pump in which a pump chamber is defined by a surface, an outer circumferential surface of the rotor, and the vane, and the oil suction passage and the oil discharge passage are respectively communicated with the pump chamber existing region, wherein adjacent vanes In the rotor portion between the storage grooves, both side surfaces of the rotor facing the inner wall surface of the housing are sloped so that the rotor thickness on the leading side in the rotor rotational direction is smaller than the rotor thickness on the lagging side in the rotor rotational direction. A vane pump characterized by having a surface inclined part.
