<p>PURPOSE: To surely supply lubricating oil to a thrust bearing while the weight of a rotator is ensured. CONSTITUTION: A notch groove 29 is formed on a weight part 28 of a lug plate 13, and lubricating oil jumped up from the groove 29 with the oscillation (oscillation clockwise in the drawing) of an oscillating swash plate 19 is supplied to a thrust bearing 18 for the lug plate. Thus, the lubricating oil can be supplied to the thrust bearing 18 for the lug plate without reduction in diameter of the lug plate 13, and the weight of a weight part can be ensured enough while seizure of the thrust bearing 18 is prevented. Accordingly, the lug plate 13 can be rotated smoothly, and furthermore, the oscillation of the oscillating swash plate 19 and the reciprocating motion of a piston 6 can be smoothed so as to obtain more efficient compressing operation.</p> |
