ABSTRACT:
A shaft is journaled to rotate in a housing and is formed with an enlarged disc which carries an elastomeric ring. As the shaft rotates, the ring is compressed against and is massaged by protrusions extending axially into the housing and coacting with the ring to apply a retarding torque to the shaft. In one embodiment, the protrusions are semispherical buttons which are formed integrally with the end wall of the housing. In another embodiment, the protrusions are spherical balls which are free to spin in semispherical pockets formed in the end wall of the housing.
