ABSTRACT:
A dynamic damper of this invention comprises: a pair of ring-shaped fixing members disposed at a predetermined interval, inserted onto and supported by a rotary shaft; a cylinder-shaped mass member having inner surface larger than the outer surface of the rotary shaft, the cylinder-shaped mass member inserted onto the rotary shaft and disposed between the pair of ring-shaped fixing members; and elastic members integrally connecting the ends of the fixing members with the ends of the cylinder-shaped mass member. The dynamic damper has enabled to down-size the configuration thereof while maintaining the performance thereof and to make the installation thereof easier.
