A structure of an accumulator of an air conditioner is provided to modify the connection pipe structure between the accumulator and compressors for recovery oil variably according to the change of a refrigerant circulation amount, and uniformly distribute oil in both directions through bidirectional branch parts for preventing the oil from being concentrated in one direction. A structure of an accumulator of an air conditioner includes a housing(151), which has a refrigerant containing space(152) defined inside, inlet pipes(153) mounted at an upper part for sucking refrigerant from evaporators, and outlet pipes(154) mounted inside to move gas refrigerant to compressors. The outlet pipe has upper and lower oil recovery holes(155a,155b) formed with a stepped difference(P2) from each other in the vertical direction, and bidirectional branch parts(156) formed with a stepped difference(P1) from each other in the vertical direction for converting refrigerant flow direction bidirectionally, reversely from the gravity direction. The upper oil recovery hole has a diameter(D1) smaller than that(D2) of the lower one.
