The stroller has a wheel (11) connected to a frame by a fork presenting an upper part for connection with the frame. Two parallel flanges (12) are perpendicular to a rotational shaft of the wheel. Each flange has an oblong hole for receiving the shaft in a manner such that the shaft is displaced at the flanges in a parallel manner and has a spring (14) whose ends are integrated to the flange and the shaft, respectively. |
