[Task] A resin-based coating layer on a swash plate of a swash-plate type compressor, particularly, a variable-displacement swash-plate type compressor should have wear resistance and low-friction property altogether. [Means for Solution] A swash plate (60) of a swash plate-type compressor is covered with a resin-based coating layer (112). The coating layer contains 5 to 60 mass% of spherical graphite particles (115b) having an average particle diameter of 5 to 50 µm, the balance being one or more species selected from polyimide resin and polyamide-imide resin. The spherical graphite particles (115b), excepting minute particles having a particle diameter 0.5 times or smaller the average particle diameter, have an average shape coefficient (Y AVE ), as defined below, falling within a range of 1 to 4, and further 70% or more in number of the spherical graphite particles have a shape coefficient (Y), as defined below, within a range of 1 to 1.5,
wherein, "total" indicates that a value in [ ] is totalized for number "i", "PM" indicates the circumferential length of one particle, "A" indicates a cross sectional area of one particle, and "i" indicates the measurement number. |
