Safety device designed to withhold the elastic support associated to the top end of the stem of a shock absorber in the corresponding seat of the body of a motor-vehicle

A safety device, designed to withhold an elastic support (4) associated to the top end of the stem (5) of a shock absorber in the corresponding seat of the body of a motor vehicle comprises a safety member (11) of the circular-plug or circular-cap type, which is positioned above the top end (82) of the outer reinforcement of the elastic support (4) projecting through a central opening (2a) of the dome-shaped portion (2) of the body of the motor vehicle. The safety member (11) is configured for engaging the aforesaid metal reinforcement and withholding it against the bottom surface of the dome-shaped portion (2) by a rotation about its axis. The safety member comprises a metal structure (110) provided with a coating made of elastomeric material (111) that covers the top wall of the metal structure (110) completely so as to close completely and in a fluid-tight way the cavity in which the stem of the shock absorber is set, also reducing the noise.
