PROBLEM TO BE SOLVED: To provide a dynamic damper of a new structure in which a resonance frequency of a mass-spring system can be set under a high degree of freedom in both axial direction and a direction perpendicular to an axis while preventing a reduction of durability of an elastic connector and an increased displacement in oscillation in a twisting direction of a mass.SOLUTION: A dynamic damper 10 comprises: a cylindrical fixing member 12 fixed to a cylindrical vibrator 28 under its inner inserted state; a mass 14 provided on an inner peripheral side of the fixing member 12; a plurality of elastic connectors 16 extending from an inner peripheral surface of the fixing member 12 toward the mass 14 formed on a periphery; and the fixing member 12 and the mass 14 being relatively connected in resiliency by a plurality of elastic connectors 16a to 16d for these members. The elastic connectors 16 are extended from the fixing member 12 toward the mass 14 with curved shape where an inclination angle in a peripheral direction in respect to a radial line is changed in a radial direction.SELECTED DRAWING: Figure 1
