Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a cylindrical dynamic damper capable of controlling a head-oscillating state of a mass member and extending the life of a connecting portion in a structure capable of lessening a spring constant of the connecting portion. SOLUTION: A cylindrical fixed portion 2 fixing a rotary shaft by externally fitting on it and the cylindrical mass member coaxially positioned with the fixed portion 2 in an outside of the fixed portion 2 are connected with each other via the connecting portion 4 made of a rubbery elastic material in the cylindrical dynamic damper, and a width of the connecting portion 4 in an axial direction of the fixed portion 2 is arranged in a small width equal to a designated length. The connecting portion 4 is formed in a state facing toward a peripheral direction while meandering to an axial direction of the fixed portion 2. COPYRIGHT: (C)2004,JPO
