ABSTRACT:
A scroll compressor has an Oldhams ring made of sintered metal operating as a rotation-prevention mechanism for holding the rotation scroll. The Oldhams ring is formed to a size to accommodate the cutting work or the grinding work of the surface processing during the forming of the sintered metal, and, as a result, the productivity of the Oldhams ring can be improved and the wear resistance becomes excellent. A scroll compressor that is inexpensive and has a high reliability may be made of a hard sintered metal which has an excellent wear resistance. A first groove 3a and the second groove 3b are formed in the end face 3 of the ring 2 of the Oldhams ring into the sintered metal. And, after the processing, the first groove 3a is deepest, and the depth is progressively reduced in order of the second groove 3b and the end face 3 in the Oldhams ring. The wear on the corner part of the tool, which is easiest to wear being used to process the side face of the keys is reduced due to the presence of these grooves.
