PROBLEM TO BE SOLVED: To provide a mounting structure of a dynamic damper which can be easily attached to and stably mounted on a propeller shaft. SOLUTION: The dynamic damper comprises a cylindrical outer pipe 2, an inner weight 3 disposed on the axis of the outer pipe 2, and a mount rubber 4 elastically connecting both, and is inserted into a hollow portion of the propeller shaft 10. A diameter-reduced part 2d is formed at both axial ends of the outer pipe 2, and an annular push washer 5 having a plurality of spring pieces 5b, 5d at inner and outer circumferential portions thereof is press-fitted into an annular space between the diameter-reduced part and the inner wall of the hollow portion of the propeller shaft. The spring pieces 5b, 5d are brought in press contact with the outer circumferential surface of the diameter-reduced part and the inner wall of the hollow portion of the propeller shaft, respectively, in such a manner that the spring pieces are sagged in the direction opposite to the press-fitting direction, thereby stably fixing the outer pipe 2.
