Abstract

A swash plate (3, 18) included in a swash plate type compressor for compressing a refrigerant is made of an aluminum alloy as a base material. Sliding contact surfaces (3a, 18a) of the swash plate (3, 18) in sliding contact with shoes (7, 19) linking the swash plate (3, 18) to pistons (6, 17) are coated with a film of a solid lubricant containing at least one lubricating material selected from molybdenum disulfide, tungsten disulfide and graphite by a transfer method. Therefore, the performance of the film and the productivity thereof are improved.
