Steering apparatus for a vehicle

摘要

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 kx 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.
