Compressor and constant speed joint

The invention provides a swash plate compressor or a swing swash plate compressor with improved reliability, by keeping a good lubrication state of a sliding part between a swash plate and a shoe or a sliding part of a detent mechanism. The swing swash plate compressor comprises: a drive shaft; a swirl plate; a swing swash plate whose rotation is prevented by the detent mechanism; a piston; and acenter shaft. The swing swash plate compressor has a device separating oil in refrigerant gas, and a high-pressure oil storage chamber storing the separated oil, and an oil guide passage is disposed to the center shaft to directly supply oil to the sliding part of the detent mechanism from the high-pressure oil storage chamber. In the swing swash plate compressor, an oil guide passage(s) is/are disposed to the drive shaft and/or a cylinder block, and the oil from the high-pressure oil storage chamber 122 is directly supplied to the sliding part between the swash plate and the shoe.
