Abstract
A cylindrical upper support interposed between a body of a vehicle and a piston rod of a shock absorber of the vehicle, including a generally cylindrical or annular inner rigid member, a generally cylindrical outer rigid member, and an elastic body interposed between the inner and outer rigid members for elastically connecting the inner and outer rigid members. The elastic body has two fluid chambers which are filled with a non-compressible fluid and which are formed in respective intermediate portions thereof as viewed in axial directions of the rigid members, such that the fluid chambers are opposed to each other in a diametric direction of the inner rigid member. One of the inner and outer rigid members has two wing members which extend in a substantially radial direction thereof into the two fluid chambers, respectively, such that each of the two fluid chambers is substantially divided by the corresponding wing member into two sections, and such that the corresponding wing member provides the each fluid chamber with a restricted part through which the two sections communicate with each other.
