Claims

[Scope of utility model registration request]

An electric motor, a rotor having vane grooves at equal intervals on its outer periphery, a race having a hole eccentric to the rotation center of the rotor, vanes or rollers that fit into the vane grooves provided in the rotor, and their lower, lower, and lower rollers. In a fuel supply pump having a plate that restricts the axial position of the race, the discharge side plate is provided with a groove having a plane symmetrical shape to the suction port provided on the suction side plate, and the discharge side plate is provided on the discharge side plate. A fuel supply pump characterized by having a groove in a suction side plate that is symmetrical with the port.
