ABSTRACT:
In a scroll compressor, a sliding direction of a Oldham coupling is defined such that an acting direction of an inertia force of the Oldham coupling is substantially opposite to an acting direction of a reaction force by gas compression, and thereby a range of fluctuation of a total torque of a first rotational torque acting on an orbiting scroll by the reaction force of gas compression and a second rotational torque of sliding movement of the Oldham coupling becomes smaller than that of the first rotational torque to suppress a noise and vibration caused by fluctuation of a rotational torque of the orbiting scroll without any limited designing of an involute shape thereof.
