PROBLEM TO BE SOLVED: To provide a dynamic damper of a compact and novel structure capable of stably achieving effective vibration damping effect to vibration of a plurality of or wide target frequency ranges even when exposed to a large temperature range. SOLUTION: A hard spring member 12 comprising metal or the like is provided, and a beam-shaped elastic deformation part 22 is composed of the spring member 12. Plural mass parts 14 and 15 are provided to be apart from each other in a length direction of the elastic deformation part 22 to compose an auxiliary vibration system having two or more degrees of freedom to a subject member 16 to be damped. In addition, damping means 28 and 30 are provided to perform damping action in vibration displacement of the mass parts 14 and 15. COPYRIGHT: (C)2004,JPO
