。[Scope of Claim for Utility Model Registration] A rotor is housed in a pump case eccentrically with respect to the pump chamber, and a plurality of vanes are arranged radially on the rotor and are held so as to be able to freely slide in and out in the radial direction. Further, an inlet port and a discharge port are provided in the pump case at positions separated from each other so as to communicate with the pump chamber, and further configured to supply lubricating oil to the pump chamber. In the vane pump, an oil drain hole is opened in the pump case at a position that is at the lower part of the pump chamber and passes through a region where the pressure chamber formed by the adjacent vanes has a maximum volume, and this oil drain hole A vane pump characterized in that the hole communicates with the outside of the pump chamber.
