A rod-damper combination comprising an oscillating rod member and a dynamic damper mounted on the rod member is disclosed. The dynamic damper (12, 38, 52, 64, 80, 110) includes a mass portion (24, 90) having a substantially cylindrical shape, and two elastic support members (26, 92) formed on axially opposite sides of the mass portion to elastically support the mass portion. The oscillating rod member (10, 50, 60) includes a small-diameter portion (20, 20a, 20b) formed at an axially middle portion of the rod member, and two large-diameter portions (22) formed on axially opposite sides of the small-diameter portion. Alternatively, the rod member (82, 106) includes a middle portion (84), and two tapered portions (88) 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. <IMAGE> |
