Zusammenfassung:A second dynamic vibration absorber is higher in resonance frequency than a first dynamic vibration absorber. At least one of the resonance frequency of the first dynamic vibration absorber or the resonance frequency of the second dynamic vibration absorber is shifted from associated at least one of the first resonance frequency or the second resonance frequency such that a peak frequency of antiresonance occurring in a higher frequency region of the first dynamic vibration absorber than the resonance frequency of the first dynamic vibration absorber is substantially different from that of antiresonance occurring in a lower frequency region of the second dynamic vibration absorber than the resonance frequency of the second dynamic vibration absorber.
