<p>PURPOSE: To positively reduce wear between a cam plate and shoes at the time of high rotation and high load by reducing sliding speed between the cam plate and shoes so as to make the PV value small. CONSTITUTION: Annular sliding plates 13, 14 are disposed between a cam plate 8 and shoes 19, 20 in such a way as to be slidable relatively to each of the shoes 19, 20 and cam plate 8, so that the sliding parts are dispersed into two places between the shoes 19, 20 and sliding plates 13, 14 and between the sliding plates 13, 14 and cam plate 8. The sliding speed between the cam plate 8 and shoes 19, 20 is lowered, and the PV value between the cam plate 8 and shoes 13, 14 becomes small.</p> |
