1. A swash plate compressor, comprising:
a drive shaft, a first swash plate coupled to the drive shaft to be rotatable integrally with the drive shaft, a second swash plate supported by the first swash plate, first shoes, which abut against the first swash plate, and second shoes, which abut against the second swash plate and receive a reaction force of compression, pistons coupled to the first swash plate via the first shoes and coupled to the second swash plate via the second shoes, and rotation of the drive shaft rotates the first swash plate, which causes the pistons to reciprocate and compress refrigerant gas,
a thrust bearing arranged between the first shoes and the second shoes and between the outer circumferential portion of the first swash plate and the outer circumferential portion of the second swash plate, the thrust bearing supports the second swash plate to be rotatable relative to the first swash plate, and a radial bearing arranged between the inner circumferential portion of the first swash plate and the inner circumferential portion of the second swash plate, the radial bearing supports the second swash plate to be rotatable relative to the first swash plate,
wherein the plate thickness of the outer circumferential portion of the second swash plate is one third or more of the plate thickness of the outer circumferential portion of the first swash plate and is thinner than the plate thickness of the outer circumferential portion of the first swash plate.
