PURPOSE: Discharge gas guide structure of an enclosed compressor is provided to prevent oil from coming in a lower muffler without extending a rotating shaft. CONSTITUTION: An enclosed compressor includes a casing(1) filled with oil; a cylinder(11) fixed to the lower part of the casing; a dividing plate(5) for diving the inner space of the cylinder into plural closed spaces; a rotating shaft(4) combined to the dividing plate together with a rotor of an electric power unit; plural vanes(6A,6B) converting the closed spaces each into a suction space and a compression space when the dividing plate turns; an upper bearing plate(21) and a lower bearing plate(22) having discharge outlets(21d,22d) to communicate with the closed spaces; and an upper muffler(31) and a lower muffler(32) reducing noise of discharge gas. In discharge gas guide structure of the enclosed compressor, discharge passages, successively penetrating the lower bearing plate, the cylinder, and the upper bearing plate, are formed. Thus, discharge gas, discharged to the lower muffler through the discharge outlet of the lower bearing plate, is discharged to the inside of the casing after passing through the upper bearing plate through the discharge passages.
