ベーン式ポンプ。[Claims for Utility Model Registration] 1. A center case, a rotor rotating within the center case, a vane held in a groove provided in the rotor, and a side plate partitioning both end surfaces of the rotor,
In a rotary vane type pump that performs pumping action by changing the volume of the space partitioned by the center case, rotor vanes, and side plates as the rotor rotates, the center case has a double structure with an inner and outer cylinder, and the inner cylinder is annular. A rotary vane pump characterized in that it is manufactured from formed thin plates and the joint between the thin plates is provided on the intake hole side of a line connecting the narrowest and widest parts of the gap between the rotor and center case. 2. The rotary vane pump according to claim 1 of the utility model registration, characterized in that the angle between the joint of the annular thin plates forming the inner cylinder and the rotor axis is deviated from parallel.
