Abstract
A steering apparatus of a vehicle can achieve detection of an absolute angle of a steering shaft with a simple structure while preventing an increase in power consumption. A resolver sensor outputs an output signal corresponding to an angular position of a steering shaft of the vehicle. A lock mechanism restricts rotation of the steering shaft at locking positions provided around the steering shaft at equal intervals. An axial multiplication angle k× of the output signal of the resolver sensor and a number N of the locking positions provided around the steering shaft satisfy a relationship represented by k≦N.
