Abstract
A swash plate type compressor having shoes provided with center holes on the slidable surfaces. The center hole provided with a bottom acts as a reservoir for lubricating oil and supplys the oil on the slidable surface of the shoe, which slides against the swash plate. There can be a second ring groove concentric to the center hole, or annexed grooves which are stretching outward radially from the center hole. The center hole also prevents the center part from protruding outward by thermal expansion, which is caused by friction. The slidable surface of the shoe is preferably coated with a layer containing solid lubricant so as to smooth the sliding motions.
