ABSTRACT:
A variable displacement type compressor having a piston accommodated in a cylinder bore, a swash plate accommodated in a crank chamber for reciprocating the piston and a drive shaft for tiltably and rotatably supporting the swash plate. The swash plate includes projections that extend toward a thrust bearing and have outer surfaces that contact the thrust bearing. A shaft hole within which the drive shaft is located between the projections. The shaft hole has an opening that opens adjacent to the projections. A recess is formed at the end of the shaft hole adjacent to the projections. A hardening method is performed on the wall of the through hole and on the outer surfaces of the projections to improve wear resistance. The hardening method prevents overheating of localized areas of the swash plate.
