摘要: A vibration damper little depending on temperature, capable of damping plural resonance vibrations over a wide frequency region as well as damping a specific frequency vibration is provided. The vibration damper comprises a housing formed of a rigid material, having an internal space and fixed to a vibration transmitting member, an elastic body inserted in the internal space not bonded thereto with a gap in a direction of vibration of the housing, and a weight integrally supported by the elastic body so as not to touch the housing. The elastic body and the weight form a dynamic damper.
