Claims

[Scope of utility model registration request]

a cylindrical casing, formed to have a smaller diameter than the inner diameter of the casing, arranged eccentrically so that a part of the outer circumferential surface has a contact portion that contacts the inner circumferential surface of the casing, and having a slit inward from the outer circumferential surface. A vane pump comprising: a rotor having a vane formed in the slit so as to be movably inserted into the slit; and an inlet port and a discharge port respectively communicating with a pump chamber between the casing and the rotor on both sides of the contact portion, At least the inner peripheral surface of the casing is formed with a permanent magnet to produce magnetic poles on the entire surface of the inner peripheral surface, and the rotor is provided with a single slit in the diametrical direction with one side open or the opposite side. A vane pump for viscous materials, characterized in that a pair of slits are formed, and the vanes are made of a magnetic material.
