Claims

[Scope of utility model registration request]

An input gear element connected to an input member receiving steering input from the steering wheel side, and an input gear element connected to the input member receiving the steering input from the steering wheel side, in a steering force transmission path that outputs the steering input input from the steering wheel to the wheels via the steering gear device. A differential gear mechanism is provided in which an output gear element connected to an output member that outputs a steering output and a reaction gear element connected to a reaction force member mesh with each other, and the reaction force member and the above reaction force member mesh with each other. In a variable steering gear ratio device having a hydraulic actuator for differential input provided to generate relative displacement between the input member and the input member, an oil pump having a discharge port and a suction port communicating with each other via a throttle; A torsion bar spring that transmits the rotation of the member to the rotation input section of the oil pump, and a torsion bar spring that is interposed in a hydraulic path between the hydraulic actuator and the hydraulic power source and that applies hydraulic pressure according to the torsion angle of the torsion bar spring. A variable steering gear ratio device comprising: a control valve configured to supply the hydraulic actuator to the hydraulic actuator.
