A bump stop device comprises a bearing 20 provided with two bottom 22 and top 24 metal washers between which rolling bodies 26 are arranged. A friction ring 34 is fixed to the first of the bottom and top metal washers and rubs against the other metal washer in order to create a static frictional torque that is greater than that of the rolling bodies and, in practice, greater than 1 Nm. The friction ring 34 makes it possible to generate a controlled resisting torque that limits the transmission to the steering column of the torque generated when driving the vehicle on a convex road.
