を特徴とする可変容量型揺動板式圧縮機。 A drive shaft supported by a cylinder block and a head member, a rocking plate attached to the drive shaft that swings as the drive shaft rotates, and a rocking plate interposed between the head member and the head member. It is equipped with a thrust bearing device that receives the thrust load generated by the rocking motion of the rocking plate, and changes the pressure in the crank chamber by communicating or cutting off the suction chamber and the crank chamber under the control of a pressure regulating valve. In a variable capacity wobble plate compressor configured to be able to vary the discharge capacity by adjusting the inclination angle of the wobble plate and changing the piston stroke, there is a space between the cylinder block and the wobble plate. A preload thrust bearing device is interposed, the outer peripheral edge of one of the thrust races of the preload thrust bearing device is brought into contact with the cylinder block, and the inner peripheral edge of the other thrust race is provided on the drive shaft. 1. A variable displacement wobble plate compressor, characterized in that the drive shaft is biased toward the thrust bearing device by contacting the stopper portion.
