The dynamic damper includes: a torque transmissible tube member (4); a mass member (2) concentrically within the tube member (4); and a pair of elastic members (3a, 3b). Both ends of the mass member (2) in the axial direction are coupled to the tube member (4) via the elastic members (3a, 3b). The mass member (2) includes a large mass section (2b) interposed between the elastic members (3a, 3b). The length of the mass member (2) in the axial direction is greater than a diameter of the large mass section (2b). From among two different bending resonance vibration modes of the tube member, a node of a higher order bending resonance vibration mode is located between the elastic members (3a, 3b). <IMAGE> |
