PURPOSE: A thrust-bearing device of a scroll compressor is provided to increase bearing power by receding a bearing area of an orbiting scroll from an orbiting center to a radial direction and accordingly to reduce friction loss in the orbiting scroll turning and the risk of overturns. CONSTITUTION: A thrust-bearing device of a scroll compressor comprises a main frame(110) fixed and installed in a casing, a fixed scroll fixed to an edge of the main frame, an orbiting scroll(120) placed on the main frame, engaged with the fixed scroll, and eccentrically combined to a rotary shaft transmitting the power of an electromotive mechanism unit, and a revolution preventing member slidably mounted in a radial direction between the main frame and the orbiting scroll to prevent the revolution of the orbiting scroll.
