A steering apparatus includes a history holding unit recording a zero point maximum value and a zero point minimum value of a steering angle of a steering wheel, a precursor determination unit, and a characteristic variation determination unit. The history holding unit cancels the recorded zero point maximum value and the recorded zero point minimum value respectively, when a predetermined period elapses following the update of the recorded value. When the precursor determination unit determines that the system is in a precursory condition to characteristic variation, the characteristic variation determination unit determines whether or not characteristic variation has occurred in the steering transmission system on the basis of at least one of an amount of increase in the zero point maximum value and an amount of decrease in the zero point minimum value following a point at which the system is determined to be in the precursory condition.
