Abstract
A power transmission mechanism for power-transmittably coupling a rotating unit of a compressor (,) composed of a drive shaft (,), a rotating support (,) and a swash plate (,) with an engine (,), comprising a pulley (,) and an armature (,), both of which constitute a first rotating body provided on a side of the engine, a hub (,), which serve as a second rotating body coupled to the drive shaft of the compressor, and a spring (,), which serves as an elastic means for coupling the first and second rotating bodies. A spring constant of the spring (,) is set such that a resonant frequency (fR) determined by the spring constant and a sum of a moment of inertia of the rotating unit of the compressor and a moment of inertia of the second rotating body as dominant factors is made smaller than a minimum frequency (f1) of torque variation produced on the compressor and more preferably smaller than a minimum frequency (f2) of torque variation produced on the engine.
