PROBLEM TO BE SOLVED: To enable preventing the phenomenon from happening in which acceleration to the transverse direction increases and the lateral turning over takes place, by giving a damping force automatically to a tracted vehicle regardless of operation, when the acceleration exceeding a specified value is detected by means of a detecting measure of transverse direction acceleration of tractor. SOLUTION: A control circuit 11 of this device takes in an output of a transverse direction acceleration sensor 12, output of rotation sensors 15-18 of right and left front wheels of tracting vehicle, output of a steering angle sensor 19, etc. And in case when the output of the transverse direction acceleration sensor 12 exceeds the first prescribed value in memory, and rotational speed difference of right and left wheels exceeds the prescribed value, a relay valve 23 is opened and closed intermittently to send brake pressure to the tracted vehicle. A timer monitors this braking condition, and when the continuingly appointed time elapsed, an output value of new transverse direction acceleration sensor is taken in, and the controlling action continues until this value falls to less than the limit. In this way, when there is a possibility of lateral turning, the tracted vehicle is surely kept in braking condition.
