A steering device of a vehicle, comprising:
- a screw shaft having two opposite ends connected to wheels and provided to be axially movable in a housing;
- a ball nut engaged with the screw shaft;
- a first nut pulley and a second nut pulley coupled to the ball nut;
- a first motor for applying torque to the ball nut through the first nut pulley;
- a second motor for applying torque to the ball nut through the second nut pulley, and
- a sensing unit for sensing a rotational angle of the ball nut,
- wherein the sensing unit includes a first gear and a second gear rotated in conjunction with rotation of the ball nut and a sensor sensing a rotational angle of the first gear and the second gear,
- wherein the sensing unit further includes a third gear rotated in conjunction with rotation of either the first out pulley or the second nut pulley, and wherein the first gear and the second gear are engaged with the third gear,
- wherein a rotational axis of the first gear is perpendicular to the axial movement of the screw shaft.
