description PROBLEM TO BE SOLVED: To provide a steering control device which reduces the driving load of a pump and improves fuel consumption performance. SOLUTION: The steering control device includes first and second solenoid valves, which are provided on first and second communication passages that communicate a rotary valve with first and second steering shaft drive portions and which change over the communication and shut-off of the first communication passage based on traveling conditions of a vehicle or a driver's driving conditions, and a third solenoid valve, which is provided on a third communication passage that connects a reservoir tank for storing hydraulic oil supplied from the pump to the rotary valve and which reduces an oil passage area of the third communication passage when the first steering shaft drive portion or the second steering shaft drive portion is driven and controlled.
