PROBLEM TO BE SOLVED: To provide a swing compressor being easily manufactured and having sufficient lubricating performance of a sliding face. SOLUTION: A piston 4 is formed by integrating a roller 2 and a blade 3 by sintering. As the man-hour in processing such as cutting of the piston 4 can be reduced in comparison with casting by applying the piston made out of a sintered material in its manufacturing process, the manufacturing can be simplified. Further as the sintered material is porous, a lubricant can be held in pores of the pistons, whereby the seizure of a sliding face of the piston can be prevented, and the performance of the swing compressor can be stably kept. As the mechanical strength is increased by infiltration of Cu on a contact part of the roller 2 and the blade 3, the fracture caused by the concentration of stress on the contact part of the roller 2 and the blade 3 in starting the switch compressor 1 and the like, can be prevented.
