(57) [Problem] To provide a rotary compressor capable of ensuring low friction, stable wear resistance and reducing weight even under severe lubrication conditions. SOLUTION: A group (Ni-PWB electroless plating film, Ni-PB electroless plating film, PTFE-dispersed Ni-P electroless plating film, diamond-like carbon film, nitride film is formed on a sliding portion. Or alumite film impregnated with PTFE) Of MoS 2 , graphite or P A vane to which a solid lubricating material containing TFE is fixed, and a sliding group A or B (alumite coating or Ni- A rotary member having the solid lubricating material adhered to one or both of the vane sliding portion and the mating sliding portion that have been subjected to the surface treatment of the P electroless plating film) and the surface treatment. compressor. |
