A vehicle steering apparatus that obtains the appropriate steering torque to the steering angle without being affected by road surface state and changes of mechanical characteristics of the steering system due to aging. The steering apparatus includes a target steering torque generating section to generate a target steering torque, a converting section to convert the target steering torque into a target torsional angle, and a torsional angle control section to calculate a motor current command value so as to follow-up a torsional angle to the target torsional angle. The target steering torque generating section includes an offset correcting section to obtain the first torque signal from a characteristic depending on the set steering angle based on an offset value of the steering torque and outputs the first torque signal as a target steering torque. The steering apparatus drives and controls the motor based on the motor current command value.
