ABSTRACT:
An upper support for a suspension system, which includes an inner rigid member having an annular wing portion, and axially opposite coned faces tapered from the wing portion to the axially opposite ends, a pair of annular rigid members disposed radially and axially outwardly of the inner rigid member, so as to face the coned faces of the inner rigid member, a pair of annular sealing rubber members fixed to the annular rigid members, and a pair of connecting rubber blocks for elastically connecting the inner rigid member and the annular rigid members. The rubber blocks partially define therebetween an annular pocket which is closed by an outer rigid member fitted on the annular rigid members via the sealing rubber members. The closed pocket is substantially divided by the wing portion into a pair of fluid chambers which are filled with a non-compressible fluid and which communicate with each other through an annular resonance portion defined between the wing portion and the outer rigid member.
