<p>The present invention discloses a vane pump. The vane pump has a liner inserted between a rotor and a casing for preventing the abrasion of the vane of the vane pump, the liner being mounted on a rotor extending portion at the front of the vane and slidably supported radially inward and outward by the vane, and a housing constituting a pumping chamber separated from the casing by surrounding the vane. If the inner surface of the elastic member contacted upon the rotation of the vane is partially worn and the pumping ability is degraded, an allowance caused by the abrasion is compensated by moving the central axis line of the housing, thereby elongating the durability of the pump without substituting parts.</p> |
