Abstract
A compressor includes pistons, each of which is coupled to a swash plate through a pair of shoes. The swash plate rotates integrally with a drive shaft. The shoes convert the rotation of the swash plate to the reciprocation of the piston. A lubricating coating made of copper-based material is formed on parts of the swash plate along which the shoes slide. The copper-based material includes silicon. The shoes smoothly slide on the swash plate, which is coated by the lubricating coating that uses minimum amount of lead.
