An upper support for a suspension system, including a generally cylindrical inner rigid member, a generally cylindrical outer rigid member, and at least one generally annular elastic body which is interposed between the inner and outer rigid members for elastically connecting these members, and which at least partially defines at least one fluid chamber that is filled with a non-compressible fluid. The upper support further includes at least one resonance member each of which is accommodated in the corresponding fluid chamber and has an outer configuration substantially corresponding to an inner shape of the corresponding fluid chamber. Each resonance member is supported by the inner rigid member or the outer rigid member, and cooperates with an inner wall surface of the corresponding fluid chamber to define a resonance portion which has predetermined dimensions, and through which the non-compressible fluid is forced to flow upon application of a dynamic vibrational load.
