Abstract
A steering apparatus for a vehicle includes at least one of an electric telescopic mechanism driving a steering wheel provided at a steering shaft and an electric tilt mechanism driving the steering wheel. The one of the electric telescopic mechanism and the electric tilt mechanism includes an electric motor, a threaded shaft connected to an output shaft of the electric motor, and a speed reduction mechanism. The speed reduction mechanism includes a worm gear, a screw gear, an idle gear meshing with the screw gear and the worm gear. The output shaft and the threaded shaft are connected to each other such that at least one of a relationship of parallelism, a relationship of inclination and a relationship of skew is established.
