PURPOSE: A shock absorber of a joint shaft is provided to protect being separated or idled by making the inner surface of a shock absorber and the outer surface of a tie rod engage with each other. CONSTITUTION: A shock absorber of a joint shaft is equipped with a shock absorber(70) taking the form of a hollow bellows for compression or extension and a tie rod(40) divided to be combine with the both ends of the shock absorber. A female spline protruded toward the center is installed on the inner surface of the open inlet port(73), to both sides of the shock absorber. A male spline(42) is installed on the insertion part(41) of the tie rod, to combine with the female spline. On the outer surface of the insertion part, plural sunk combining grooves are made and on the inner surface of the inlet port, plural combining protrusions are made to be insert in the combining part. The combining of the shock absorber and tie rod is solid and the intensity in shock is improved and therefore separating and idling of the shock absorber and the tie rod is protected.
