ことを特徴とするリツプパツキン。 A lip packing is installed in a pair of packing mounting grooves spaced apart in the axial direction, and the lip packing has a generally U-shaped cross-section and is arranged so as to open in directions away from each other. One end in the direction has an annular main lip that presses against the sliding surface and a bottom lip that presses against the bottom of the mounting groove, and spacer means that protrudes beyond the main lip in the axial direction creates a constant distance between the main lip and the side wall of the mounting groove. An annular grease reservoir groove partitioned by an annular sub-lip is formed behind the main lip in the axial direction, and the radial height of the annular sub-lip is approximately aligned with the radial height of the sliding surface.
A lip packing characterized in that a notch is formed in the annular sub-lip to communicate the annular grease reservoir groove with the space between both lip packings.
