Claims

[Claims for Utility Model Registration] A rotor that rotates integrally with a rotating shaft, a cam ring that surrounds the rotor and has an inner cam surface, and a vane that is held on the rotor so as to be able to come into sliding contact with the inner cam surface of the cam ring. In the vane pump, the cam ring is constructed by assembling two or more cam ring members having inner circumferential cam surfaces of the same shape with their end surfaces closely pressed together, and the cam ring member has a notch formed in its end surface. . A vane pump characterized in that when the cam ring members are assembled in close contact with the end surfaces of each other, a hole formed by the opposing notches is used as a suction port.
