A spring element (7) acting in the vertical direction upon the rear wheels (12) of a wheel-chair is connected to the frame (1) of the wheel-chair via a supporting pipe (3), on the one hand, and to the axletree of the wheel-chair via a supporting pipe (5) for the axletree bearing (6) on the other hand. The supporting pipes (3, 5) which are arranged one above the other are located coaxially to a guiding rod (2) fixed to the wheel-chair frame (1) and thereby include the spring element (7). <IMAGE>
