Abstract
A seal member for a joint between a pivot member movable about a rotational axis of a shaft includes a ring, a flange, and a resiliently flexible intermediate portion interposed therebetween. The ring includes annular distal and proximal ring faces disposed in spaced relationship to each other along a longitudinal axis. The flange includes a pair of flange faces disposed in spaced relationship to each other along the longitudinal axis. The flange includes outer and inner flange surfaces extending along the longitudinal axis between the pair of flange faces at, respectively, outer and inner flange perimeters thereof. The intermediate portion has a ring end that circumscribes, and is connected to, an outer circumferential ring surface of the ring and a flange end that is connected to the inner flange surface of the flange such that the ring is relatively movable with respect to the flange.
