ABSTRACT:
A power transmission apparatus for a compressor used in an air conditioner for a vehicle including a damper mounted to one side of a pulley rotated by a driving power transmitted from an engine wherein the damper and an elastic portion is formed between an outer ring and an inner ring, and wherein a mounting flange of the outer ring is coupled to the pulley and a mounting flange of the inner ring is coupled to a limiter. The limiter has a plate shape and comprises: a middle portion in a ring shape, an outside portion in a ring shape around the edge of the middle portion, and a neck portion connecting the middle portion and the outside portion, whereby upon overload, the neck portion is broken. The middle portion of the limiter is coupled to a hub, and the hub penetrates the center of the inner ring and is coupled to the limiter between the damper and the pulley.
