Abstract

The shock absorber body (1) which may be of metal, has a resilient cushion comprising a central part (2) of self-lubricating plastics material, surrounding the pivot (3) and a peripheral part (4) of resilient plastics material, secured to the shock absorber body (1). The resilience of the peripheral part (4) of the cushion is chosen to provide a preset reduction of the pivot (3) in response to a shock in both the axial and radial directions. The peripheral part (4) is moulded around the central part (2) of the cushion and it is preferably secured in the shock absorber body as it sets.
