板潤滑油供給構造。 A swash plate is fitted and fixed to a drive shaft rotatably supported by a cylinder block, and thrust bearings are interposed between both end surfaces of the boss portion of the swash plate and the cylinder block, and an oil pump installed on the rear side In a swash plate compressor, oil pumped from an oil storage chamber is supplied to the thrust bearing via an oil supply passage formed on the drive shaft, from the oil supply passage formed at the axial center of the drive shaft to the outer periphery of the drive shaft. A pair of branch paths whose ends open at positions corresponding to the central portion of the swash plate boss portion in the surface are formed so as to extend in mutually opposite directions while intersecting the axis of the drive shaft, and the swash plate boss portion A swash plate lubricating oil supply structure for a swash plate compressor is provided, in which passages of the same length having discharge ports at positions corresponding to both thrust bearings are provided symmetrically to each other so as to communicate with each of the branch passages.
