Claims

[Scope of utility model registration request]

In a dynamic damper in which a mass body 3 is held via an elastic member 2 on a bracket 1 which is subjected to vibrations in the vertical direction, a through hole 4 penetrating vertically through the mass body 3 is provided, and the through hole 4 is press-fitted into the through hole 4. The elastic member 2 is formed between the outer sleeve 5 and the inner sleeve 6, and the inner sleeve 6
One end of the strut member 9 inserted through is fixed to a holding surface 7 larger than the through hole 4 of the bracket 1, and a retaining plate 10 larger than the through hole 4 is provided at the other end of the strut member 9, A dynamic damper characterized in that the mass body 3 is held at a predetermined distance from the holding surface 7 of the bracket 1 and the holding plate 10, respectively.
