摘要： There is provided a steering apparatus to ease an uncomfortable feeling given to an operator when a steering wheel is connected to a steering mechanism, on a fail. The apparatus includes a unit that varies an angular ratio of a steering angle of front wheels with respect to an operational angle of a steering wheel. The apparatus also includes a connection unit such as a electromagnetic clutch for connecting the steering wheel to the steering mechanism in order to fix the angular ratio, on a fail such as a failure of a steering motor. The apparatus also includes a rotational body which relatively rotates with respect to the steering wheel by an angular deviation upon this connection. Accordingly, since a real neutral position of the steering mechanism coincides with a neutral position recognized by a pattern on the rotational body being seen, it eases the uncomfortable feeling onto the operator.

摘要： An electric motor provided in a vehicle steering apparatus includes a stator coaxially surrounding a steering shaft, an inner rotor disposed on the inner periphery of the stator, and an outer rotor disposed on the outer periphery of the stator. The facing area between the stator and the rotor can be increased by providing the inner rotor and the outer rotor in the electric motor. Consequently, the electric motor can be miniaturized while a certain output thereof is maintained. The vehicle steering apparatus can be miniaturized by miniaturizing the electric motor.

摘要： A planetary gear apparatus whose gears are all constituted by continuous shifted gears. A backlash between the input sun gear and each of the input side planetary gears is adjusted by pressing a second carrier plate supporting each integrated pair of the input side planetary gears and the output side planetary gears and moving it in the axial length direction by a ball bearing by a screwing operation of an adjusting nut. A backlash between the output sun gear and each of the output side planetary gears is also adjusted by pressing the output sun gear and moving it in the axial length direction by the ball bearing by the screwing operation of the adjusting nut. Accordingly, the backlash of all meshing portions can be adjusted during or after completion of the assemblage.
