ABSTRACT:
An improved swash-plate type compressor including a pair of thrust bearings interposed between the swash plate and central seat portions provided on the cylinder blocks forming the outer frame of the compressor, characterized by that a retainer is interposed between the bearing ring of each of said thrust bearings on the cylinder block side and associated one of said central seat portions, wherein the bearing ring has a periphery thereof formed with at least one engaging cut, while the retainer has opposite end faces thereof formed with at least one first engaging protuberance and at least one second engaging protuberance for engagement with said engaging cut and an associated end of corresponding one of spaces axially formed through the cylinder blocks, respectively. Rotation of said bearing ring can thus be prevented with respect to the central seat portion of the cylinder block to avoid abrasion in the opposed faces of the two members.
