Claims

[Scope of utility model registration request]

In a vane pump, a cam ring, a rotor disposed within the cam ring for relative rotation, and a cover having an outer circumferential portion fixed to one end surface of the cam ring and an inner circumferential portion slidingly contacting one end surface of the rotor; a pressure retainer having an outer circumference fixed to the other end surface of the cam ring and an inner circumference slidingly contacting the other end surface of the rotor in order to cooperate with the cam ring and the cover to maintain pressure within the cam ring; In order to transmit the driving force of the drive shaft to the rotor, the rotor is attached to the drive shaft via a spline portion, and when the rotor tilts and rotates with respect to the drive shaft, the rotor In order to prevent seizure between the end face and the end face of the cover or pressure retainer, the spline portion is formed such that the tooth width gradually increases in the longitudinal direction toward the center in the width direction of the rotor. A vane pump with gradually increasing tooth width at the center of the spline.
