PROBLEM TO BE SOLVED: To effectively reduce noise resulting from the resonant vibration of a vehicle constituent member when attaching a dynamic damper to the vehicle constituent member, so that the occupant hardly feel the noise.SOLUTION: In a dynamic damper 20 for a vehicle, a vibration level with respect to a frequency of vibration forms a resonant waveform having peaks lower than a peak of a vibration level at a resonant frequency Fa of a vehicle constituent member 6 at a low-frequency side and a high-frequency side by being attached to the vehicle constituent member 6 for suppressing the vibration of the vehicle constituent member 6 which resonates with vibration from a vibration source. A set frequency Fb of the dynamic damper 20 which generates a downward peak between the peak at the low-frequency side and the peak at the high-frequency side in the resonant waveform of the vehicle constituent member 6 is located at the low-frequency side rather than the resonant frequency Fa.SELECTED DRAWING: Figure 5 |
