A scroll-type compressor includes a fixed and an orbiting scroll each having an end plate. A ball coupling means preventing the orbiting scroll from rotating, includes a first race and a second race and a plurality of balls. The balls are engaged between ball rolling grooves on the first race and ball rolling grooves on the second race. Each of an interior circular portion and an exterior circular portion of the first race and the second race is connected to the orbiting scroll and the front housing. Each of a clearance is created between the first race and the orbiting scroll, and between the second race and the front housing. The structure for the scroll-type compressor according to this invention may reduce the number of parts compared to known scroll-type compressor, and may maintain stability of an orbital motion of an orbiting scroll, when thrust load is high.
