Can be selected. That is, as shown in FIG. 3A, a large diameter portion 11 of the inner cylinder 3 is formed by press-fitting a shaft 7 having a diameter larger than the inner diameter of the end of the inner cylinder 3. The fitting end of the shaft portion 7 is formed with a tapered portion 7a for increasing the inner diameter of the inner cylinder 3. When the connection reliability cannot be sufficiently obtained with this structure, as shown in FIG. 3B, an annular groove 12 is formed near the end of the shaft portion 7 and the large-diameter portion of the inner cylindrical body 3 is formed. By crimping the edge of 11 and press-fitting a part of the edge into the annular groove 12, it is possible to irremovably couple.

The shaft portion 7 is press-fitted and fitted to 15. Further, as shown in FIG.
A small-diameter portion 16 is formed at the end of the shaft portion 7, and the small-diameter portion 16 is press-fitted and joined to the small-diameter portion 15 of the inner cylinder 3. Thus, whether the diameter of the shaft portion 7 is larger than the inner diameter of the inner cylindrical body 3,
Depending on whether it is small, the amount of meat of the elastic body 8 can be changed, and there is an advantage that characteristic tuning can be performed not only with the mass 9 but also with the elastic body 8.
