ABSTRACT:
A double-mass type dynamic damper mounted on a rod-shaped oscillating member, which includes a first damper system and a second damper system that are tuned to two different frequency ranges. Each of the damper systems includes a cylindrical mass member disposed radially outwardly of the oscillating member, and an elastic support member for elastically supporting the mass member with respect to the oscillating member. The elastic support members of the two damper systems are disposed in series and connected to each other in the axial direction. The dynamic damper further includes an elastic connector formed by adjacent parts of the two elastic support members, for elastically connecting axially opposed faces of the two mass members. The two elastic support members have respective spring constants as measured in the radial directions, which spring constants are both larger than a shearing spring constant of the elastic connector that is subjected to shearing stresses upon relative displacement of the mass members in the radial directions.
