ABSTRACT:
A rod-damper combination comprising an oscillating rod member and a dynamic damper mounted on the rod member is disclosed. The dynamic damper includes a mass portion having a substantially cylindrical shape, and two elastic support members formed on axially opposite sides of the mass portion to elastically support the mass portion. The oscillating rod member includes a small-diameter portion formed at an axially middle portion thereof, and two large-diameter portions formed on axially opposite sides of the small-diameter portion. Alternatively, the rod member includes a middle portion, and two tapered portions on axially opposite sides of the middle portion. The two elastic support members of the dynamic damper are mounted on the two large-diameter or tapered portions of the oscillating rod member, respectively.
