Abstract

PURPOSE: To improve sealing property by providing concavo-convex patterns on a truncated-cone surface on the side of oil of the tip part of the lip, not on the contact side thereof, and by enhancing following performance of the lip with the flexible deformation and repulsive force of the tip part of the lip given by the provision of the patterns.
CONSTITUTION: The concavo-convex parts R1 and R2 are provided on the truncated-cone surface 2 on the oil side of the lip 1. By this provosion, the influence of skin cure can be removed in the case when the lip is molded completely. In addition, the flexible repulsive force is given by the deformation of rubber located in the tip part 5 of the lip 1, whereby the sealing property is enhanced.
