Abstract
A vibration restraining apparatus for vehicle of the present invention is comprised of a housing formed by a rigid material and having an inner space, and fixed to a vibration transmitting member; a filled member sealed in the inner space of said housing in a non-adhered state with leaving a gap with respect to a vibrating direction of said housing, and formed by an elastic body at least at a surface thereof. When the housing resonates by vibration transmitted from the vibration transmitting member, the filled member contacts inner surface parts located at both sides of the housing in a vibrating direction thereof to exercise a damping character due to an energy loss caused by a sliding friction and a collision. Thus, a large damping character occurs inside of the housing to reduce vibration of the housing effectively. As a result, vibration of the vibration transmitting member is effectively reduced. The vibration restraining apparatus for vehicle of the present invention can be lightened in weight, does not have a temperature dependency, and can exercise the vibration restraining effect for plural resonances having different frequencies.
