るベーンポンプ。[Claims for Utility Model Registration] It has a cam ring, vane, rotor, and side plate built inside, and has a shaft hole connected to the connecting hole of the rotor, and a shaft seal is provided on the open end side of the shaft hole to the outside. The housing has a seal and the inside of the shaft seal is connected to the suction passage of the pump, and the housing is inserted into the shaft hole to form a shaft chamber between the shaft hole and is rotatably supported by the housing. In the vane pump, the vane pump is equipped with a drive shaft that rotationally drives the rotor, and in which hydraulic oil leaked from the side surface of the rotor is returned to the suction passage through the shaft chamber. A vane pump characterized in that the clearance between the shaft chamber and the drive shaft is set to a predetermined small value.
