Abstract: PURPOSE:To prevent a coupling being pressed in one direction, to reduce abrasion of each member and to improve pump efficiency by balancing pressure around the coupling connecting a driving shaft to an inner rotor. CONSTITUTION:The capacity of a pressure chamber formed by an outer rotor 33 and an inter rotor 34 which can be rotated eccentrically to each other is reduced gradually proceeding from the side of a suction port 41 to the side of a discharge port 39. A coupling 23 is engaged with the end of a shaft 21 at parallel two-face part of the inner wall and engaged with an inner wall groove 34a of the inner rotor 34 at a projection part. At the projection part of the coupling 23, pressure balance holes 23g and 23h are formed for making the peripheral high pressure side communicate to the low pressure side in the axial direction. Thus, the pressure difference between the high pressure side and the low pressure side around the coupling 23 is solved by the pressure balance holes 23g and 23h, contact force between the coupling 123 and a casing 36 is relaxed and abrasion is reduced.
