PURPOSE: A lubricating device of a scroll compressor is provided to achieve improved performance by reducing friction losses, while preventing abrasion and heating of thrust surface. CONSTITUTION: A lubricating device comprises a rotating shaft having an oil feeder arranged at the lower portion of the rotating shaft so as to feed the oil contained in the bottom of a closed container(101) to an oil pocket(104) of an upper frame(102) through an oil flow channel; the oil pocket for containing the oil fed through the oil flow channel; the upper frame having an oil storage part for storing the oil fed from the oil pocket to the thrust surface of the upper frame; and a swirling scroll(135) having a rear surface slide contacting the thrust surface of the upper frame. The swirling scroll has an oil passage groove formed at the rear surface of the swirling scroll so as to feed the oil from the oil pocket to the oil storage part of the upper frame. Thus, the thrust surface of the upper frame and the rear surface of the swirling scroll contact with each other in a fluid lubricating state.
