Claims

[Scope of utility model registration request]

A torque generator, which generates rotational force using hydraulic pressure, is fixed between the steering shaft and the input shaft of a reduction mechanism consisting of gears, etc., and the input shaft of this torque generator is connected to the steering shaft, and the output shaft is connected to the input shaft of the reduction mechanism. A wheel steering device that is connected to an input shaft, and has a pitman arm provided on the output shaft of the speed reduction mechanism and a knuckle arm of a steering wheel, which are pivotally connected by left and right drag links.
