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.

Vibration damper

Disclosed is a vehicle tire structure in which a tubeless pneumatic tire is fitted over a wheel, characterized in that: at least a pair of walls project in substantially radial direction from an outer circumferential surface of the wheel into an annular chamber defined between the tire and the wheel. These walls prevents the generation of standing waves or the air column resonace inside the tire and contribute to the overall reduction of the road noise of the vehicle. The proximal ends of the walls may be either bonded to an annular member which surrounds the wheel or pivoted to a similar annular member and biased into radial or upright positions by a spring member, in such a manner as not to interfere with the replacement of the tire. Alternatively, the walls may consist of inflatable bags which may be inflated into upright positions and deflated into flat positions.
