(54) Swash plate type compressor


(57) The sliding characteristics of the sliding portions, where components slide on each other, are improved and the work of coating forming thereof is simplified. DLC coatings (43) and (44) are formed on a front surface (39) and a rear surface (40) of a swash plate (22) by a CVD method or a PVD method. Therefore, the sliding characteristics of the sliding portion (47) between the swash plate (22) and shoes (27) and (28) are improved and abrasion or seizure occurs less frequently on the surface of the swash plate (22) and flat surfaces (35) and (36) of the shoes (27) and (28).
