Drive shaft damper

摘要

A vibration and noise attenuating damper for an automotive drive shaft has a cylindrical body of such size as snugly to fit within the shaft between its reduced diameter ends and be retained in fixed position. The damper has at each end thereof a seal which bears against the surface of the bore of the shaft. The seal has a wall which is accommodated within the tubular body of the damper. The seal may include an impervious closure which closes the end of the damper. The inner surface of the tubular damper body may be formed of a waterproof material.
