ABSTRACT:
A seal for use between two relatively-rotatable parts includes a sealing member of fluorine resin having a side which terminates in an edge and which has a plurality of recesses adjacent to and disposed about the edge. Each groove is in the form of a quadrilateral with two opposite sides substantially parallel to the edge, one being longer than, and closer to the edge than, the other, and each of the other two sides being inclined at an acute angle to the longer of the two parallel sides. In use the edge and at least part of the side adjacent the edge are engageable with one of the two relatively-rotatable parts.
