A dynamic damper for absorbing vibrations in a rotary driveshaft, including a cylindrical mass member having an inner surface and an outer surface, a plurality of elongated connecting members each connecting member each connecting member extending radially inwardly from the inner surface of the mass member thereby defining a plurality of spaced apart attachment surfaces wherein the cylindrical mass member is affixable to the rotary driveshaft such that the plurality of spaced apart attachment surfaces contacts the rotary shaft, the mass member spaced apart from the rotary shaft and supported by the connecting member to allow the mass member to vibrate by resonance and the connecting members being subjected to compressive deformation between the mass member and the rotary shaft.
