Abstract
PURPOSE: To raise the lubricating property and durability of a seal lip, by providing two-layer helical ribs at opposite oblique angles within a prescribed width of contact of the seal lip with a shaft.
CONSTITUTION: The seal lip 1 is provided with the two-layer helical ribs r, R at the opposite obliquie angles within the prescribed width of contact of the seal lip 1 with the shaft. When the shaft rotates in a direction A, oil is actuated by the helical ribs r only in a region (a) and pulled back as shown by an arrow (c). When the shaft rotates in another direction B, the oil once pulled in the region (a) flows back and is sucked as shown by another arrow D.
