PURPOSE:To prevent wear and damage due to lopsided contact between an Oldham's ring and a block by forming plural oil sumps on the top of a projecting part for receiving the key of said Oldham's ring, formed on a block and connecting said oil sumps to each other by means of a groove. CONSTITUTION:A projecting part 3a having a groove 3b for receiving the key 6b of an Oldham's ring 6, is formed on the top of the block 3 of a scroll compressor, while oil sumps 7 are formed on both sides of the groove 3b of the projecting part 3a respectively. Both of the oil sumps 7 are connected to each other via a groove 8. Thereby, the supporting area between the bottom face of the annular part of the Oldham's ring 6 and the projecting part 3a of the block can be increased, while oil can be stably fed, preventing the generation of damage due to wear in a sliding part. |
