ンプのベーン構造。[Claims for Utility Model Registration] A solid cylindrical rotor is arranged eccentrically on the inner periphery of a cylindrical cylinder, and a pair of vane grooves are provided facing each other in the radial direction of the rotor. A structure in which the vanes are slidably held within the cylinder, and the fluid supplied into the cylinder is compressed and transferred from the suction side to the discharge side while being confined by each vane by the alternate retraction and protrusion movement of each vane as the rotor rotates. In this pump, a blind hole is formed through the axial center of the rotor, and each vane groove is formed so that the bottom of the vane groove passes through the blind hole so as to face 180 degrees in the radial direction of the rotor. are slightly shifted toward the lag side in the rotational direction with respect to the axial center of the rotor, so that the penetrating tips of the respective vane grooves are alternately shifted and intersected with respect to the axial center of the blind hole, and each vane A notch is formed at the bottom of the vane, and when one vane is recessed into the vane groove, the step formed by the notch comes into contact with the shoulder of the other vane groove, so that the retracted position of the vane is set by printing. A vane structure of a fluid transfer pump characterized in that the vane structure is made as shown in FIG.
