いう問題がある。A conventional double-mass type damper has a rubber-like elastic body which is interposed between a hub and each mass body and which is adhered to both members, and is divided into each mass body and is provided as a separate component. When manufacturing a damper, 2
There is a problem that it takes time and effort to manufacture because it has to be molded and adhered repeatedly. If the double-mass damper is disk-shaped, a mass body is connected to each of the axial end surfaces of the disk-shaped hub via rubber-like elastic bodies, and five parts are connected in series in the axial direction. However, there is a problem that the occupied width of the damper in the axial direction becomes too large.

変更することが可能である。The damper shown in FIG. 1 has a rubber-like elastic body (8) on the inner diameter side.
Is adhered to the cylindrical portion (2) of the hub (1) and the inner surface of the inner diameter side disc portion (4) and the outer surface and end surface of the inner diameter side mass body (6), and the rubber-like elastic body on the outer diameter side ( 9) is the cylindrical portion (2) of the hub (1) and the outer diameter surface and the outer diameter side disc portion (5)
Is bonded to the end surface of the outer diameter mass and the inner diameter surface and the end surface of the outer diameter side mass body (7). Therefore, the mass bodies (6) and (7) act on torsional vibrations because the rubber exists in parallel with the axis (torsional damper), and the bending vibrations occur because the rubber exists at right angles to the axis. Functioning as a bending damper and functioning as a torsion bending damper for each of the double masses, the rubber-like elastic bodies (8) and (9) are bonded to the hub (1) and the mass bodies (6) and (7). The function can be changed as in the example below.
