Abstract:
1. A power transmission apparatus for a compressor, comprising: a pulley rotated by driving power transmitted from an engine; a hub connected to a driving shaft of a compressor, for transmitting the driving power transmitted through the pulley to the driving shaft; a limiter having a plate shaped configuration disposed between the pulley and the hub, for transmitting power and cutting off power transmission between the pulley and the hub when load exceeds a predetermined value in the compressor; and a damper connected to the limiter and the pulley, for absorbing impact due to a torque change, the damper comprising wherein the limiter is adapted to cut off power transmission by breakage of a neck portion formed between the inner ring and the hub, wherein the limiter, in its plate shaped configuration, comprises: wherein the mounting flange is formed to extend towards the center of the inner ring by a predetermined width, such that the mounting flange covers the limiter so as not to be exposed to the outside.
