  • Device for reducing noise produced by automotive vehicle components
    Patent number: 5631451
    Abstract: A retaining plate is disposed along and spaced apart by a predetermined distance from the surface of a noise source in an automotive vehicle component so as not to be displaced away from the surface of the noise source. A sheet-like elastic member is compressedly interposed between the noise source and the retaining plate. As a result, the effect of reducing the noise due to vibration is attained without substantially increasing the weight of the automotive vehicle components and without adversely affecting the sealability and other performances required to the components.
