PURPOSE: A traction control device of a vehicle is provided to control traction precisely and reliably by directly detecting force between wheels and a driving shaft with a SAW(surface acoustic wave) torque sensor. CONSTITUTION: A traction control device comprises plural SAW torque sensors(2A-2D) installed between driving shafts and wheels to detect driving force; a comparator(32) detecting the minimum operation by comparing each action between the driving shafts and the wheels from the SAW torque sensors; a throttle sensor(30) outputting an opening degree detecting signal by detecting the opening degree of the throttle valve; a control unit(34) controlling traction of the wheel with the lowest action from the comparator according to the opening degree detecting signal; a throttle actuator(36) regulating inflow of air by the control unit; a brake driving unit braking the lowest action wheel according to traction control from the control unit; and a traction display unit indicating the traction control state corresponding to the display control from the control unit.
