ンプ。 A rotor fixed to one end of a cantilever rotating shaft having a horizontal axis is rotatably disposed within a liner fitted to the inner surface of a casing, and the rotor is provided with vane grooves orthogonal to each other at the axis. A vane is attached to each of these grooves so as to be slidable along the rotor radial direction, and the flow path inside the liner has the same cross-sectional area from the fluid intake port on the outer periphery of the rotor to the fluid discharge port. In a vane pump set to The rotor has a short cylindrical receiving part and a shaft mounting part, the rotor is solid, the shaft mounting part has a mounting hole concentric with the rotating shaft, and a keyway is provided on the inner surface of the hole, The receiving part is provided with a stepped bolt hole that is concentric with the rotating shaft and passes through the bottom wall of the mounting hole, the shaft is fitted into the mounting hole and secured with a key, and a wrench hole is provided in the end surface of the shaft. A vane pump characterized in that a bolt having a head is inserted into the bolt hole and screwed together through the bolt hole.
