摺接面の一方又は両方に形成されて、前記ポンプ
室内部の作動油の一部を前記摺接面間に導く導油
溝を具備することを特徴とするベーンポンプ。[Claims for Utility Model Registration] Comprising a cam ring sandwiched on both sides by a pair of side plates and a rotor housed coaxially inside the cam ring, the cam ring is introduced into a pump chamber formed between the two. In a vane pump that increases the pressure of hydraulic oil by rotation of the rotor while slidingly contacting both side plates, the vane pump is formed on one or both of the sliding surfaces of the rotor and the side plates, and is located inside the pump chamber. A vane pump comprising an oil guide groove that guides a portion of the hydraulic oil between the sliding surfaces.
