Abstract: (125) A scroll compressor is disclosed. The scroll compressor includes a rotating shaft coupling portion (153) axially extending from a central portion of an orbiting end plate (151) to radially overlap an orbiting wrap (152), such that an eccentric portion (1251) of a rotating shaft (125) is coupled thereto, and a portion of the orbiting wrap may extend from an end surface of the rotating shaft coupling portion (153) facing a fixed end plate (141). With the configuration, a distance between bearing reaction force and gas reaction force acting on the orbiting scroll can be reduced, to stabilize a behavior of the orbiting scroll and thus reduce back pressure, thereby decreasing friction loss between scrolls. Simultaneously, compression chambers can be formed even in a central portion of the orbiting scroll (150), which can increase a compression ratio and improve volumetric efficiency.
