PROBLEM TO BE SOLVED: To provide a steering gear for a vehicle for suppressing oscillation/divergence of a steering wheel by adding a feedback control amount based on deviation between a target steering angle and an actual steering angle to a command value of reaction force control. SOLUTION: The steering gear for the vehicle comprises a steering wheel angle detecting means 12, a reaction force torque detecting means 10 for detecting a reaction force torque applied to the steering wheel 1, a wheel steering angle detecting means 11 for detecting a wheel steering angle, a target reaction force generating means 15 for generating a target reaction force as a target value of the reaction force torque, a reaction force torque controlling means 16 for driving and controlling a sub steering mechanism so as to match the target reaction force with the detected reaction force torque, a target wheel steering angle generating means 13 for generating a target steered angle of steered wheels, a steering mechanism driving means 9 for controlling a steered wheel controlling mechanism, a wheel steering angle controlling means 14 for driving the steering mechanism driving means so as to match the target wheel steering angle with the output of the wheel steering angle detecting means, and a wheel steering angle compensating means 17 for adding the feedback control amount based on the deviation between the target steering angle and the output of the wheel steering angle detecting means to the output of the reaction force torque controlling means 16.
