An automotive vane pump for generating anti-centrifugal force, and more particularly to an automotive vane pump for generating anti-centrifugal force adapted to maintain constant discharge pressure and discharge amount regardless of rotating speed to prevent power loss and to improve durability via stable operation, the pump comprising: a stator housing a rotor radiately equipped with a plurality of blades variably withdrawn according to size of centrifugal force generated by being rotated and coupled to a shaft received in a housing having inlet/outlet structure of operation oil in coupling with a pulley driven by an engine; a cover coupled to the housing mounted with the stator for sealing up the housing; and centrifugal force generating means mounted at the rotor 5 for generating centrifugal force in order to pull the blades into the rotor relative to radial withdrawal of the blades, where the centrifugal force generating means further comprises: a resilient member constituting a spring radiately formed at the rotor, equipped at a slot accepting the blades and compressed by movement of the blades; and a ball pendulum exposed to a centrally-opened communicating groove through a connecting groove connected to the slot where the blades are accommodated.
