To provide a fixed displacement piston compressor provided with both of a function preventing relative rotation between a thrust race and a cylinder block, and a function limiting a function as a passage of a specific communication passage.

This compressor includes a cylinder block 11 including a plurality of cylinder bores 40 arranged around a rotary shaft 32, a swash plate integrated with the rotary shaft 32, pistons accommodated in the plurality of cylinder bores 40, a swash plate chamber accommodating the swash plate, a housing joined to the cylinder block 11 and including a suction chamber and a delivery chamber, a plurality of communication passages 39 connecting the swash plate chamber with the suction chamber, a thrust bearing disposed between the cylinder block 11 and the swash plate, and thrust race anti-rotation mechanisms 71, 72 preventing rotation of the thrust race 63 on a cylinder block 11 side provided on the thrust bearing with respect to the cylinder block 11. The thrust race anti-rotation mechanisms 71, 72 restrict a certain communication passage 39 of the plurality of communication passages 39.
