A vane pump having an electric drive unit with a drive shaft, a pump chamber, a rotor arranged in the pump chamber so as to rotate about a rotational axis, and a driver that has at least one driver pin and is connected in a rotationally fixed manner to the drive shaft, wherein, in an operating state of the vane pump, the driver pin, by way of a contact surface of the driver pin designed as a section of a lateral surface, engages in a torque-transmitting manner with a contact surface of the rotor delimiting a rotor recess designed to correspond to the driver pin. In order to improve a vane pump, it is proposed that the contact surface of the rotor is designed and arranged in such a manner that the rotational axis lies in the contact surface when this contact surface is hypothetically extended toward the rotational axis.
