<P>PROBLEM TO BE SOLVED: To provide a dynamic damper that can suppress generation of abnormal noise or microvibration and can also prevent deterioration of durability. <P>SOLUTION: The dynamic damper includes: a pendulum vibration damping mechanism 5 that damps, by reciprocation of the mass body 6, a torsional vibration generated in a rotator 2 where a torque limiter mechanism 12 for limiting torque transmission is provided when an excessive torque is input; and a fixation unit 9 that fixes the mass body 6 when the torque limiter mechanism 12 restricts the torque transmission. Accordingly, as the fixation unit 9 fixes the mass body 6 when the torque limiter mechanism 12 is actuated, abnormal noise or microvibration that are generated when the mass body 6 collides with an inner wall surface of a housing chamber 7 for housing the mass body 6 can be prevented or suppressed, and the deterioration of the durability of the pendulum vibration damping mechanism 5 or the dynamic damper can be prevented. <P>COPYRIGHT: (C)2013,JPO&INPIT |
