PROBLEM TO BE SOLVED: To provide a vehicular steering device reducing a load applied on a transmission ratio variable mechanism, and achieving downsizing. SOLUTION: The transmission ratio variable mechanism 5 is interposed between a third shaft 13 and a fourth shaft 14 of a steering shaft 3 in a vehicular steering device 1. The transmission ratio variable mechanism 5 changes a transmission ratioθ2/θ1 which is a ratio of a steering angleθ2 of steering wheels 4L, 4R to a steering angleθ1 of a steering member 2. In a power transmission path L from the steering member 2 to a steering mechanism 10, a transmission ratio variable mechanism motor 23 and a steering auxiliary motor 25 are disposed in this order. Rotor centers of both of the transmission variable mechanism motor 23 and the steering auxiliary motor 25 are coaxially disposed with the steering shaft 3. COPYRIGHT: (C)2010,JPO&INPIT
