摘要： A scroll compressor is provided. The scroll compressor may include a discharge cover that separates a suction space and a discharge space of an airtight container. The discharge cover may be inserted into a fixed scroll so as to be fixedly coupled thereto, thereby reducing an amount of components, such as a gasket and fastening bolts required to fix the discharge cover, and an assembly time to assemble components, reducing production overall costs. Also, as fastening bolts are not used, a width corresponding to a space for bolts may be reduced in the fixed scroll, whereby a phenomenon in which the fixed scroll is heated by a discharge refrigerant within the discharge space may be reduced, thereby reducing suction loss of the refrigerant sucked into the compression chamber and improving compressor efficiency. Also, a size of the fixed scroll may be reduced, thereby reducing a weight of the fixed scroll, and a weight of the overall compressor.
