Abstract: PROBLEM TO BE SOLVED: To provide a steering gear box mechanism for a vehicle supplying fluid to a fluid control means of the steering gear box mechanism on the basis of the running state of the vehicle. SOLUTION: This steering gear box mechanism 1 for the vehicle supplies the fluid to the fluid control means 7 on the basis of the running state of the vehicle. That is, when the vehicle stops or runs at a very low speed, the steering gear box mechanism 1 sends the fluid to a steering mechanism 2, the driving of the mechanism 2 is supported. Accordingly, a driver can steer efficiently. Moreover, when the vehicle runs at a high speed, the driver can steer without any trouble. Accordingly, to support the mechanism 2 is stopped. In this case, the steering mechanism 2 is disconnected from a pump 5. The operation is performed by changing the flow direction of the fluid flowing from the pump 5, evading the fluid control means 7 and returning the fluid to a reserver 9. Therefore an engine drives the pump 5 continuously, but does not support the steering mechanism 2.
