<p>PURPOSE: To provide a power transmission structure in a compressor which mitigates the fluctuation of the load torque on the compressor side and transmits the torque to a vehicle engine side, and blocks the transmission of the excessive load, whose load torque is stable in the blocking and whose constitution is simple. CONSTITUTION: A driving force transmitting body 38 is screwed to a rotary shaft 34, and tightened and fixed by a lock nut 39. An annular buffer rubber 42 is interposed between the driving force transmitting body 38 and a pulley 36. Revolution of a vehicle engine is transmitted to the pulley 36 through a belt 37, and rotation of the pulley 36 is transmitted to the rotary shaft 34 through the butter rubber 42 and the driving force transmitting body 38. When the load torque on the compressor side is excessive, projections 42a, 42b are detached from storing recessed parts 40b, 41b, and the pulley 36 is in the idling condition relative to the driving force transmitting body 38.</p> |
