ABSTRACT:
In a variable displacement swash plate type compressor, there is employed a structure for stopping or minimizing a turning movement of a piston about its axis. The structure comprises a given part of the piston which is always out of the corresponding cylinder chamber; a turn stopper portion formed on the given part and including laterally opposed sides each having a rounded outer surface; and a cylindrical surface defined in a casing of the compressor at a portion which faces the turn stopper portion. The cylindrical surface is so arranged as to make a surface-to-surface contact with one of the laterally opposed sides when the piston is turned about its axis by a given angle.
