In a reaction torque calculation process, an electronic control unit (34) included in a steer-by-wire steering device (10) is configured to calculate a distributed axial force (T3) obtained by distributing an angle axial force (T1) and an electric current axial force (T2) based on a final distribution ratio (Rf). The reaction torque calculation process includes at least one of a first abnormal-time process and a second abnormal-time process. The first abnormal-time process is executed to hold, for calculation of the angle axial force (T1), a vehicle speed signal value (Vh) immediately before the vehicle speed signal (V) becomes abnormal. The second abnormal-time process is executed to hold, for calculation of a normal-time distribution ratio (Rn), a vehicle speed signal value (Vh) immediately before the vehicle speed signal (V) becomes abnormal or hold a value (Rnh) of the normal-time distribution ratio (Rn) immediately before the vehicle speed signal (V) becomes abnormal, and then gradually change the final distribution ratio (Rf) to an abnormal-time distribution ratio (Ra).
