A resilient biasing device comprises inner (32A,B) and outer sleeves (34A,B) around an annular elastomeric member (30). The inner sleeve defines fixing points substantially coplanar with the axis of the assembly. The assembly is then cut perpendicular to its axis, and one of the two pieces rotated about an axis neither coplanar nor perpendicular to that defined by the fixing points and the outer sleeve portions of the two sub-assemblies joined. The fixing points are then realigned with the object to be resiliently biased, thus torsionally preloading the two subassemblies in opposite directions. <IMAGE> |
