Abstract
Abstract A vehicle steering apparatus includes a steering wheel which has an annular boss portion with an axis and is rotatably supported on a vehicle body side member, a steering shaft, and a non-rotatable member provided in the steering wheel, which is coupled to the vehicle body side member by shafts. The rotation of the steering wheel is transmitted to the steering shaft by a mechanism including a pinion portion having an axis, formed at an end portion of the steering shaft on a side of the steering wheel, and a ring gear portion having an axis, formed on an inner surface of the boss portion and meshed with the pinion portion, the axis of the ring gear portion being eccentric with the axis of the pinion portion and concentric with the axis of the boss portion. The coupling member extends through a gap between the ring gear portion and the pinion portion.
