ABSTRACT:
A primary objective of the present invention is to decrease the friction coefficient of the sliding face of a sliding element and to improve its seal performance. The sliding element disposes a plurality of elongate dimples in the outer circumferential region and the inner circumferential region relative to a boundary reference line and the inclination of the dimples located in the outer circumferential region is different from that of the dimples located in the inner circumferential region. The longitudinally forward edge of the outer circumferential dimples relative to a rotational direction is inclined toward the outer circumference and the longitudinally forward edge of the inner circumferential dimples relative to a rotational direction is inclined toward the inner circumference.
