An oil feeding structure of a scroll compressor is provided to stably support an orbiting scroll in spite of inconsistent pressure change due to bearing area loss generated by orbiting motion of an orbiting scroll. An oil feeding structure of a scroll compressor includes an upper frame formed with a plurality of oil grooves(46) at a top surface, an orbiting scroll secured on the top surface of the upper frame and carrying out orbiting motion, and a fixed scroll fixed at an upper part of the orbiting scroll for compressing fluid. A thrust bearing surface(54) of the orbiting scroll surface-contacts a conservation bearing surface(47) of the upper frame during the orbiting motion, so that the orbiting scroll is supported in spite of high pressure generated at the top part of the orbiting scroll.
