<p>PROBLEM TO BE SOLVED: To reduce the weight of a piston for a swash plate type compressor. SOLUTION: A piston 14 includes a neck part 80 and a head part 82, the head part 82 includes a main unit part 128, external peripheral side slide part 130, and an internal peripheral side slide part 132. The internal peripheral side slide part 132 is formed in symmetrical shape relating to a plane including the center axial line of the piston 14 and the rotational center axial line of a swash plate. In this way, whichever a rotational direction of the swash plate may be, local wearing can be well suppressed. The head part 80 and the internal peripheral side slide part 132 are connected by a rib 135, but for no connection in an external peripheral side, weight of the piston can be reduced by a degree of this connection.</p> |
