Abstract
A propeller shaft for a vehicle includes a shaft having locking protrusions on an outer circumference, a tube having locking grooves on an inner circumference into which the shaft is inserted, the locking grooves engaging with the locking protrusions to form the spline coupling, a dynamic damper inside the tube to correspond to an end of the shaft and absorbing vibrations transmitted from a driving system, and a rubber stopper interposed between an outer circumference of the dynamic damper and the inner circumference of the tube to support the dynamic damper and correspond to the end of the shaft to limit sliding of the tube at normal times. The rubber stopper is broken by a pushing operation of the tube when an impact load greater than a collapse load of the rubber stopper acts on the rubber stopper, thereby permitting the sliding of the tube.
