PROBLEM TO BE SOLVED: To provide a dynamic damper 1 assuring a high productivity and structured suitably to reduce the torsion vibrations. SOLUTION: The dynamic damper is equipped with a mass 11 with the center of gravity located eccentrical nearer one end 11a in the axial direction and inserted into a hollow shaft 22 of a propeller shaft, a first resilient piece 12 installed on the peripheral surface of the mass 11 in a position nearer the end 11a and consisting of a rubber-form resilient material to be put in pressure contact with the inner surface of the hollow shaft 22, and a second resilient piece 13 installed on the peripheral surface of the mass 11 in a position nearer the other end 11a in the axial direction and consisting of a rubber-form resilient material to be put in pressure contact with the inner surface of the hollow shaft 22. The first resilient piece 12 is formed split in a plurality of segments in the circumferential direction and thereby is equipped with a lower spring constant than the second resilient piece 13.
