Abstract

A scroll compressor is characterized in that by reducing an Oldham ring 57 and an orbiting scroll 12 in size, a compressing mechanism 4 is reduced in size, a pair of scroll-side keys 57b are disposed at locations deviated from each other from a diameter line of the ring portion 57a so that a distance between the pair of scroll-side keys 57b becomes not less than a width of the scroll-side keyway 12d, and a pair of main bearing-side keys 57c are disposed at locations deviated from each other from the diameter line of the ring portion 57a so that a distance between the pair of main bearing-side keys 57c becomes not less than a width of the main bearing-side keyways 51a.
