Abstract
For reducing vibrations having different frequencies and transmitted to a chassis of a vehicle, a vibration-proof apparatus mounted on a support member supporting a vibratory body on the chassis includes a first dynamic damper and a second dynamic damper secured to the support member, such dynamic dampers being arranged to absorb vibrations having different frequencies. The apparatus is particularly applicable to a subframe which undergoes vibrations from a differential device and from a propeller shaft.
