PROBLEM TO BE SOLVED: To provide a steering device constituted by restraining occurrence of a tire slipping angle at the time of turning and improving steering stability and operability by correcting a relation of a steering angle ratio so that an ackerman or parallel characteristic is strengthened as steering quantity in a front wheel steering car and a front and rear wheel steering car becomes larger. SOLUTION: It is devised to correct an inner and outer wheel steering angle ratio larger and smaller in accordance with increase of steering quantity by deciding an electric current value to an electric motor 14 and driving an electric current driver 20 by a CPU (central processing device) in accordance with output signals of a steering angle sensor 18 actuated by rotation of steering and a rotational angle sensor 19 of the electric motor 14. |
