<P>PROBLEM TO BE SOLVED: To provide a vane pump having a simple structure which can be manufactured by simple work. Ž<P>SOLUTION: In the vane pump 1, a rotatably and pivotably supported rotor 4 is provided in a casing 2, a vane storage part 7 extends to a base body part 5 of the rotor 4 along the radial direction of the rotor 4, a slidable vane 8 is stored in the vane storage part 7, a ring member 3 is arranged on the outer circumferential side of the vane 8, and the vane 8 slides in the vane storage part 7 associated with the rotation of the rotor 4 and is slidably brought into contact with an inner circumferential surface 3a of the ring member 3. The base body part 5 of the rotor 4 is formed in a substantially cylindrical shape, and an annular rubber 41 formed in an annular shape is arranged on the inner circumferential side of the base body part 5. When the rotor 4 is rotated, the vane 8 is pressed by the annular rubber 41 from the inner circumferential side to the outer circumferential side. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
