<p>PROBLEM TO BE SOLVED: To provide a dynamic damper 10 capable of preventing change in properties caused by adhesion and deposition of mud or the like.SOLUTION: A dynamic damper 10 includes a hub 1 attached to a rotating shaft, an annular mass body 2 arranged on an outer peripheral side of the hub 1, and a plurality of elastic connecting bodies 3 made of a rubber like elastic material and disposed between an outer peripheral surface of the hub 1 and an inner peripheral surface of the annular mass body 2 at prescribed intervals in a circumferential direction so as to mutually connect the hub 1 and the annular mass body 2. The dynamic damper 10 further includes an easily bendable and displaceable protrusion 6 positioned between the elastic connecting bodies 3, 3, provided on the outer peripheral surface of the hub 1, and having an end 6a adjacently opposed to the inner peripheral surface of the annular mass body 2.</p> |
