PURPOSE:To reduce vibration and noise and improve the wear-resistivity by forming a retainer out of foamed plastics reinforced with carbon fiber and holding a plurality of balls which are put between both the back face of the mirror board of a turning scroll at the reverse side of the lap thereof and a block. CONSTITUTION:A scroll type compressor having a turning scroll 4 and a fixed scroll 5 which have involuted laps 4b and 5b standing upright on mirror board 4a and 5b, respectively, also has a self-turn preventing mechanism 6 which prevents the turning scroll 5 from turning of itself and has it make orbital action. A plurality of balls 15m are put between the mirror board 5a of the turning scroll 5 and a block 3 to which the fixed scroll 4 is fixed, and the held in respective retainer holes 16m of a retainer 16 so as not to contact with each other. In this case, the retainer 16 is made out of foamed plastics reinforced by adding carbon fiber, which is 15mum or less in diameter and 1mm or less in length. |
