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.
Claims14
A mounting structure of a dynamic damper for mounting, on a vibration body of a vehicle, the dynamic damper including a bracket fixed to the vibration body of the vehicle, a pair of plates protruded from the bracket along a first direction and opposite in a second direction perpendicular to the first direction, a mass member having a mass body connected to the pair of those plates through rubber elastic bodies and disposed between the opposite faces of the pair of the plates, the bracket including an opening openingly formed between the opposite faces of the pair of the plates, and the mass member including a main body inserted into the opening and steps protruded from the main body in the direction perpendicular to the first direction and inhibiting the fall-off of the mass member through the opening,
- wherein the mounting structure includes an inhibition member disposed to be opposite to the outer face of the mass member on the opposite side to the bracket side,
- wherein the opposite interval between the inhibition member and the mass member in the first direction is set to be smaller than the insertion allowance of the main body with respect to the opening so that even if the mass member comes into contact with the inhibition member, the insertion state of the main body with respect to the opening is maintained, and
- wherein the plates and the inhibition member are configured as separate members.
