Title: SEAL RING
Abstract:
Provided is a seal ring configured so that both a reduction in friction loss and the prevention of oil leakage can be simultaneously achieved. A seal ring is provided with an inner peripheral surface, an outer peripheral surface, side surfaces, a plurality of pockets, and recess regions. The outer peripheral surface faces the inner peripheral surface. The side surfaces are perpendicular to both the inner peripheral surface and the outer peripheral surface. The plurality of pockets are provided in the side surfaces so as to be separated from each other. The recess regions are provided in the side surfaces and comprise a plurality of independent recesses. In this seal ring, the oil buffering function of the recess regions can simultaneously achieve both a reduction in friction loss and the prevention of oil leakage.
