ABSTRACT:
A variable contact seal mechanism which includes a rotatable shaft, a seal body having a wall member, and a seal member having a cylindrical portion secured onto the rotatable shaft and a tongue portion resiliently slidably contacting the seal wall such that continuous resilient contact force of the tongue portion with the wall is changed in response to rotational speed of the shaft. A bearing member is utilized which rotatably supports the shaft along with a mechanical sealing mechanism mounted so as to surround the shaft wherein the seal member is disposed between the bearing and the mechanical sealing mechanism.
