PURPOSE: A rotation force increase apparatus is provided to reduce the friction between leakage prevention members using the pressure of fluid.;CONSTITUTION: An endless track(10) is assembled with a screw of chain shape, and transmits the power by having an orbit circling motion. A first sprocket(30) is rotated with the power of the endless track. A second sprocket(70) is transmitted the torque of the first sprocket through the endless track. A screwnut type rotator forms a pressure chamber. The endless track is pressed with the rotating operation consolation. A leakage prevention member installs on the upper end of the pressure chamber. The leakage prevention member flexibly adheres closely to a helical blade.;COPYRIGHT KIPO 2010
