PURPOSE:To permit to prevent seizing of contacting surfaces by a method wherein a multitude of recesses for lubricating oil reservoirs are provided on the slidingly contacting places of a side plate and a rotor. CONSTITUTION:A ball indent 10 is provided with a configuration capable of keeping the lubricating oil 12 substantially by the surface tension of the oil. The ball indents 10 are formed on the predetermined surface at many spots, therefore, the seizing of the slidingly contacting surfaces of the rotar 2 and the side plates 5 may be prevented effectively under a condition that the supply of the lubricating oil is poor or the oil is not supplied like the time of starting of the rotary compressor. |
