Lubricating apparatus of a scroll-type compressor comprising a thrust bearing surface provided on a main frame, the surface including a lubricating groove thereon, an orbiting scroll performing an orbital motion under the condition of slide contacting at a lower surface thereof with the thrust bearing surface, a crankshaft having an axial lubricating passage, and lubricating passage included in the orbiting scroll and communicating with the axial lubricating passage of the crankshaft. The lubricating passage comprises a horizontal passage being radially formed as outwardly extending from the inner center of the orbiting scroll and including a stop pin which is inserted into the outer end of the horizontal passage, and also a lower vertical passage being vertically formed as extending from the horizontal passage in order to communicate with the lubricating groove of the main frame. The lubricating apparatus of this invention has advantages in that it simplifies the construction of the compressor, reduces the manufacturing cost, and facilitates the assembling process of the compressor.
