Abstract
An oscillating piston type compressor has a piston formed integral with a blade. The compressor accommodates in a casing a compression mechanism section and a motor section, the mechanism including the piston having a plate-shaped blade integrally formed on a cylindrical portion is fitted onto an eccentric portion of a crankshaft to perform orbital motion relative to an inner peripheral surface of a cylinder, the plate-shaped blade being formed at its radial end surface with a recess or a protrusion, which serves as a reference of position.
