Abstract: A suspension support capable of reducing remarkably noise ascribable to vibration transmitted from tires to the cabin inside, in particular, noise due to tire cavity resonance is provided, which comprises an inner attachment member to be attached to an upper end portion of a rod of a shock absorber, an outer attachment member surrounding the inner attachment member and to be attached to a car body side, and a vibration-isolating base of rubber-like elastomer interposed between these members. To that end, an actuator as vibration exciting means driven by means of electromagnets is provided and connected to the upper end portion of the rod so as to excite the rod in its axial direction.
