Swash plate type compressor
 A swash plate type compressor, in which there is incorporated a plurality of double-headed compressor pistons, each being formed with an axially central recess between two heads thereof. Inside the recess a generally outer part of the swash plate is arranged so as to establish an operative connection between each piston and the swash plate. The axially central recess has a bottom surface a part of which protrudes toward an outer surface of the swash plate. The protruding part serves to restrict a rotation of each piston about its own axis to a given small amount. The protruding part has an axial length determined so that when each compressor piston approaches one of the two compression dead centers, an outer edge of the swash plate comes away from the protruding part.
