ヘサ勢したことを特徴とする可変容量形ベーンポンプ。A movable ring that accommodates a rotor having a large number of vanes is accommodated in the inner hole of the pump housing so as to be able to swing in the radial direction via an axial pivot pin provided in the pump housing, and In a variable displacement vane pump, the movable ring is swung by a pushing member movably assembled in a radial direction on a portion opposite to the pivot portion, thereby changing the amount of eccentricity of the movable ring with respect to the rotor. , a pair of locking slits in the axial direction are formed in a diametrical portion of the outer periphery of the movable ring, one locking slit is engaged with the pivot pin, and the other locking slit is connected to the pushing member. A pressing member is assembled on the pivot pin side of the pump housing to be in elastic contact with the outer surface of the movable ring, and the pressing member is engaged with the engaging pin connected to the movable ring. A variable displacement vane pump characterized in that the engaging pin side is biased.
