1. A steering apparatus for a vehicle comprising:

  • a controller which a driver manipulates for steering;

    a first device for detection of an amount of manipulation rendered to the controller;

    a second device for detection of an amount of steering of steerable wheels;

    a control unit for controlling the amount of steering based on at least the amount of manipulation detected by the first device; and

    a third device for applying a reaction force to the controller in a direction opposite to a direction of the manipulation according to a signal delivered by the control unit, wherein the steering apparatus further comprises a sensor for detection of a speed of the vehicle, and the control unit determines the reaction force by multiplying a deviation between the amount of manipulation and the amount of steering by a coefficient for vehicle speed, which is adapted to be larger as the speed of the vehicle detected by the sensor increases.
