1. A dynamic damper, comprising:a mass member assembly including a plurality of discrete mass members, each mass member having an inner surface, and an outer surface, said inner surface and outer surface form a coating that covers each mass member entirely, and a first and second affixing member for affixing the mass member to another mass member of the assembly, said first and second affixing members including a first and second tab arranged on one of said mass members and a first and second receptacle arranged on the other of said mass members, the mass member assembly being affixable to a rotary shaft. 2. A dynamic damper as in claim 1, wherein one of said affixing members comprises one of said tabs for receipt by one of said receptacles of another mass member. 3. A dynamic damper as in claim 1, wherein one of said affixing members comprises one of said receptacles for receipt by one of said tabs of another mass member. 4. A dynamic damper as in claim 1, wherein the mass member assembly is cylindrical in shape when in the assembled position. 5. A dynamic damper as in claim 1, wherein said mass members are made of a steel material. 6. A dynamic damper as in claim 1, wherein said inner surface, said outer surface and said affixing members are made of an elastic material. 7. A dynamic damper, comprising:a mass member assembly including a plurality of mass members, each mass member having an inner surface extending from said mass member, and an outer surface, said inner surface and outer surface form a coating that covers each mass member entirely, the mass member assembly being affixable to a rotary shaft; anda plurality of elongated connecting members each molded integrally with and extending radially inwardly from the inner surface of each mass member toward the rotary shaft thereby defining a plurality of spaced apart attachment surfaces, wherein each of the plurality of spaced apart attachment surfaces secures the damper in the closed position to the rotary shaft, the mass member assembly being spaced apart from the rotary shaft and being supported by the connecting members directly contacting the shaft to allow the mass member assembly to vibrate by resonance, and the connecting members being subjected substantially to compressive deformation between the mass member assembly and the rotary shaft. 8. A dynamic damper as in claim 7, wherein the rotary shaft has a central axis of rotation and each of the plurality of spaced apart attachment surfaces is aligned in a direction substantially parallel thereto. 9. A dynamic damper as in claim 7, wherein the connecting members are equidistantly spaced apart from each other along the inner surface of each of the mass members. 10. A dynamic damper as in claim 7, wherein the connecting members, the inner surface, and the outer surface are formed from an elastic material. 11. A dynamic damper as in claim 10, wherein the elastic material is rubber. 12. A dynamic damper as in claim 7, wherein each mass member is insert molded integrally with the connecting members. 13. A dynamic damper as in claim 7, wherein the connecting members are generally rectangular in shape and extend along at least 25% of the
