The invention relates to an arrangement for resilient suspension of a cab with respect to a vehicle frame, and a bushing which forms part of the arrangement. The cab is connected to the vehicle frame by means of a number of spring struts (1) which are anchored in elements (11) fixed to the cab via a bushing (4) which filters out body noise within the frequency range 80-300 Hz with amplitudes of up to 2-3 mm. These types of vibrations are not kept up with by shock absorbers, because of internal friction and hysteresis. The rubber bushing (4) is arranged on a suspporting sleeve (6) which is anchored to the spring strut (1) and which is clamped between two stop surfaces (5, 14). The supporting sleeve (6) has an axial length (SL) which exceeds the corresponding axial length (BL) of a rubber element (40). The bushing is dimensioned so that under static load due to the service weight of the cab there is a clear distance (a1, a2) between the stop surfaces (5, 14) and the axially directed surfaces (41, 42) of the bushing.
