とするベーンポンプ。[Claims for Utility Model Registration] A pump housing having a hollow chamber with both ends open, an end plate that closes one open end of the hollow chamber, a cam ring housed in the hollow chamber, and a cam ring that clamps the cam ring. a first side plate and a second side plate arranged on both sides of the cam ring; a pressure acting chamber formed between the end plate and the first side plate; and a pressure chamber rotatably housed within the cam ring. A rotor having a plurality of vanes held on its circumference in sliding contact with a cam surface, one end of which is connected to the rotor through the second side plate, and the other end of which protrudes from the other open end of the hollow chamber. a shaft; a spring interposed between the first side plate and the end plate; and a ball bearing fitted into a bearing hole formed at the other open end of the hollow chamber to support the rotating shaft; In the vane pump, the first side plate is urged in the direction of the rotational axis by the pressure of the pressure oil flowing into the pressure action chamber and the elastic force of the spring, and is brought into pressure contact with the cam ring, wherein the second side plate is attached to the bearing hole. and for controlling the position of the ball bearing and the second side plate in the direction of the rotation axis by a snap spring engaged in the bearing hole, and for supporting the rotation axis within the second side plate. A vane pump characterized by a metal bearing.
