Abstract: PURPOSE: An axial leakage prevention structure is provided to reduce manufacturing procedures and cost by preventing leakage through the centrifugal force of a rotor. CONSTITUTION: An axial leakage prevention structure is characterized in that a sliding bush(15) to be inserted into a boss(8a) of a swirling scroll(8) is formed to be inclined, and an eccentric portion of a crank shaft(6) to be coupled to the sliding bush is formed to be inclined so as to correspond the inclined portion of the sliding bush. Thus, when power is applied and the crank shaft rotates, centrifugal force is generated which allows the slide bush to be raised by the inclined surface formed at the eccentric portion of the crank shaft. Then, the slid bush presses the upper surface of the inner periphery of the boss of the swirling scroll by the centrifugal force, and axial gaps(G1,G2) between the swirling scroll and a fixed scroll(7) are minimized, to thereby minimize leakage of a compression unit.
