PURPOSE: A device for lubricating rotation preventive device for scroll compressor is provided to lubricate a frictional part between an inner surface of a groove of a rotary scroll and an upper protrusion of an oldham ring, contacting the inner surface of the groove. CONSTITUTION: A device includes a lubricant storing device, placed on either an upper protrusion(42) of an oldham ring(40) or a groove(20a) formed on a bottom of a rotary scroll(20) to store lubricant; and a lubricant supplying device, supplying lubricant, supplied from a journal bearing, to the lubricant storing device by rotating movement of the rotary scroll by rotation of a crank shaft. The lubricant storing device has more than one concave(42a) on one side of either the upper protrusion of the oldham ring or the groove formed on the bottom of the rotary scroll to store lubricant. The lubricant supplying device is a groove(35a) formed on an upper surface of a thrust bearing(35) of a fixed frame(30), contacting with the bottom of the rotary scroll.
