Claim 0:
1. A steering device to be mounted on a vehicle, the steering device comprising:
a power steering unit disposed below a floor of a vehicle cabin, the power steering unit including a gear structure that amplifies a rotational force input from an input shaft, and including an output shaft connected to a pitman arm that moves a drag link, the output shaft outputting the amplified rotational force to the pitman arm;
a coaxial motor provided below the floor of the vehicle cabin and directly above the power steering unit and including an output shaft arranged coaxially with an input shaft of the power steering unit;
a reactive force motor provided above the floor of the vehicle cabin to be mechanically separated from the coaxial motor to be mechanically unconnected with the coaxial motor;
a steering shaft connected at one end to a steering wheel and connected at another end to the reactive force motor, the steering wheel being disposed above the floor of the vehicle cabin; and
a control device that calculates a rotational direction and a rotation amount based on a torque and a steering angle of the steering wheel, controls the coaxial motor and the power steering unit to achieve the rotational direction and the rotation amount, and controls the reactive force motor to apply a reactive force to the steering shaft according to the rotational direction and the rotation amount.
