PROBLEM TO BE SOLVED: To provide a vehicular steering device capable of facilitating the driving of a vehicle by taking into consideration the degree of familiarity of a driver to a steering characteristic of the steering device. SOLUTION: An electronic control unit 36 inputs a detection value from each sensor in a Step S11. In a Step S12, a coefficient Nk_0 of familiarity for indicating the degree of familiarity to the steering characteristic of a driver is determined by using the input detection value. In a Step S16, when the coefficient Nk_0 is close to "0", a small target turning angleδd is calculated, and when the coefficient Nk_0 is close to "1", a large target turning angleδd is calculated. In a Step S17, when the coefficient Nk_0 is close to "1", a time constantτof a turning actuator 21 is set to be a large value, and when the coefficient Nk_0 is close to "1", a small time constantτis set. In a Step S18, when the coefficient Nk_0 is close to "0", large reaction force torque Tz is calculated, and when the coefficient Nk_0 is close to "1", small reaction force torque Tz is calculated.
