PROBLEM TO BE SOLVED: To provide a vehicular steering device capable of determining an accurate motor angular velocity arithmetic operation value. SOLUTION: This vehicular steering device has a motor for assisting steering torque applied to a steering shaft of a vehicle and a control device 8 controlling the motor, and also has a motor angular velocity arithmetic operation means 24 arithmetically operating motor angular velocityωm, a vehicle state detecting means 23 detecting a vehicle state of indicating an angle of a traveling wheel of the vehicle, an offset quantity arithmetic operation means 25 arithmetically operating an offset quantityωdist of the motor angular velocityωm based of the motor angular velocityωm and the vehicle state, and a motor angular velocity correction means 26 correcting the motor angular velocityωm based on the offset quantityωdist.
