PROBLEM TO BE SOLVED: To provide a vehicular steering device capable of performing simple driving by realizing the vehicular steering characteristic in a very low speed zone having excellent responsiveness. SOLUTION: An electronic control unit 35 calculates the turning angleδof right and left front wheels FW1 and FW2 with respect to the steering angleθinput in a steering wheel 11 based on the proportional map to indicate the predetermined linear relationship if the vehicle speed V is equal to or lower than the predetermined value. The proportional map has a linear relationship between the maximum steering angleθmax capable of turning the steering wheel 11 and the maximum turning angleδmax capable of turning the right and left front wheels FW1 and FW2, and a driver can drive a vehicle at a very low speed. Further, the operation quantity of the steering wheel 11 by the driver is reduced, the right and left front wheels FW1 and FW2 can be turned with excellent responsiveness, and the vehicle can be easily driven at a very low speed.
