  • Patent number: 11964525
    Abstract: A mounting structure of a dynamic damper capable of effectively reducing the vibration of a vibration body is provided. The mounting structure includes a suspension member 100 inhibiting the upward shift of a mass member 5. The suspension member 100 and plates 3 are configured as separate members, so that as compared with the case where a pair of plates 3 are coupled, the opposite interval between the plates 3 can be determined without being affected by the dimension accuracy of such the coupling portion. Thus, the thicknesses of the rubber elastic bodies 4 can foe formed at high accuracy, so that the mass member 5 can be easily vibrated at the desired frequency. Therefore, the vibration of the suspension member 100 can be effectively reduced.
