A resilient support device for the stem of a shock-absorber of a motor-vehicle suspension, in particular for a suspension having a MacPherson type architecture, comprises a bushing made of elastomer material (4) operatively interposed between a structure (3) fixed to the upper end of the stem of the shock-absorber and a structure (5) fixed to the bodywork of the motor-vehicle. The bushing of elastomer material (4) is shaped such that it is subject to a uniform shearing stress following a relative axial movement of said structures (3, 5). Furthermore, the bushing (4) presents opposite front surfaces (4a) which cooperate with cam-shaped surfaces (7a, 9a) of the structure (5) fixed to the bodywork of the motor-vehicle, such that their contact extends progressively through an increasing area, starting from the peripheral outer edge, radially inwardly. as the relative movement (in an axial and/or radial direction) of said structures between which the bushing is interposed increases.
