Abstract
A compressible spring includes a substantially solid body defining a central axis and manufactured from an elastomeric material. A substantially solid abutment upstands axially on one end of the substantially solid body. There is also a lip that is disposed on a distal end of the axial abutment in a plane being substantially transverse to the central axis. An axial bore may be provided extending through the thicknesses of the body and abutment. Furthermore, a plate shape member may be provided that is mechanically secured to the substantially solid body during the forming process, wherein the abutment is passed through a central aperture in the rigid member and wherein the lip cages a thickness portion of the rigid member around the central aperture.
