ABSTRACT:
A swash-plate type compressor provided with a pair of thrust bearings arranged at opposite ends of the swash plate to support thrust loads caused by the swash plate. The thrust bearings each comprise a plurality of seats in the form of blind holes formed in end faces of central seating portions formed on the cylinder blocks and a plurality of bearing members each having its one end portion slidably fitted in a corresponding one of the seats. The seats or blind holes are formed in the end face of each central seating portion along the perimeter of the opening of a drive shaft-fitted axial hole formed in the central seating portion and in a circumferentially spaced arrangement. The bearing members each have its other end portion formed with a planar end face and have this planar end face disposed in slidable face-to-face contact with a corresponding end face of the boss of the swash plate.
