STEERING DEVICE FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a steering device for a vehicle capable of miniaturizing and reducing the weight of an electric actuator and improving the energy efficiency of the whole of the vehicle without complicating a structure thereof by conducting auxiliary steering with the usage of a hydraulic pressure for braking in a state of steering without driving when varying a steering angle by the electric actuator. SOLUTION: A steering angle is varied by transmitting movements of the steering electric actuator M to a wheel 4f. In a state of steering without driving, hydraulic oil can be supplied to a hydraulic actuator 21 for generating a steering auxiliary force from a pump in a hydraulic pressure supply unit A. In a state other than steering without driving, the hydraulic oil can be supplied to a brake device 54 from the pump through a hydraulic pressure distribution unit B.
