Abstract: A swash plate type compressor includes a cylinder block having a crank chamber, a rotary shaft, a swash plate, pistons and fasteners extending through the crank chamber between any two adjacent pistons. The cylinder block further includes ribs projecting inward from inner surface of the crank chamber, extending in axial direction of the rotary shaft and being arranged so that the pistons and the fasteners are positioned alternately between any two adjacent ribs, a piston-side wall surface forming the inner surface and being positioned between any two adjacent ribs located on opposite side of the piston and a fastener-side wall surface forming the inner surface and being positioned between any two adjacent ribs located on opposite side of the fastener The piston-side wall surface is spaced farther away from the rotary shaft than the fastener-side wall surface in radial direction of the rotary shaft.
