The shock absorber consists of a hemispherical cup (1) which fits between the socket (3) and support (4). The cup has a thin wall (10) and a series of annular projections (11,12) forming steps. The middle projection (11) in the base of the cup is higher than the others (12) around it, and the height of the cup is less than that of the socket which fits (9a), it. The annular projections around the cup have a semi-circular cross-section and engage with the convex surface of the socket as an increasing pressure is applied to it and as the central projection deforms.
