ABSTRACT:
Fixed scrolls 4, 5 are supported so to be movable axially relative to an orbiting scroll 6, so that a proper space is kept between wraps 4a, 5a and 6a to avoid an excessive load in the contacting area. Further, an end portion of an outer curve of the wrap 6a of the orbiting scroll 6 is formed to come close to or coincide to an outer edge of a panel 6f of the orbiting scroll 6 and an Oldham's coupling is accommodated in a concave groove 6e formed on an outer circumference surface of the panel 6f, so that the size of the scroll compressor is reduced.
