Title: Seal device having a flexible finger seal member

Abstract: A seal device for creating a seal between a rotatable shaft and a stationary member. The seal device includes a seal member having a generally annular body including a generally cylindrical inner wall forming a bore that extends through the body and a sealing surface adapted to rotatably and sealingly engage the stationary member. The body includes a generally annular flexible finger seal member having a base attached to the body and a generally circular peripheral tip that defines an aperture. The bore of the seal member and the aperture of the finger seal member are adapted to receive the shaft such that the tip of the finger seal member is in static sealing engagement with the shaft. A coupling member is adapted to attach the seal member to the shaft for conjoint rotation therewith and to resiliently bias the sealing surface of the seal member into rotating sealing engagement with the stationary member.
