Abstract A variable displacement compressor that prevents inclination of a lug plate when the displacement is less than the maximum displacement. A thrust bearing 61 is located between the lug plate 17 and the front housing member 11. The thrust bearing 61 is annular and centered on the axis L of the drive shaft 16. The thrust bearing 61 receives a compression load F applied to the lug plate 17 from pistons 22 through a swash plate 18 and a hinge mechanism 19. The radius 11 of the thrust bearing 61 is greater than the distance between the contact point of the hinge mechanism 19 and the axis L of the drive shaft 16 when the inclination of the swash plate 18 is maximized. Therefore, the compression load F is applied within the radius of the thrust bearing, which reduces noise and vibration.
