A steering device according to one aspect of the disclosure includes: a speed reducer configured to decelerate a rotational power input from one surface side while increasing a torque and output rotation from an output section disposed on the other surface side; a motor provided on the one surface side and configured to input the rotational power to the speed reducer; and a control device for controlling the motor. The motor includes a rotor for generating the rotational power. The rotor includes a rotor output shaft disposed coaxially with an output axis of the output section. The motor inputs the rotational power from one end side of the rotor output shaft to the speed reducer. The control device is disposed on the other end side of the rotor output shaft coaxially with the rotor output shaft and includes a sensing unit for sensing rotation of the rotor.

An electric power steering apparatus according to the present embodiments comprises an input shaft connected to an steering shaft, a first output shaft coupled to the input shaft, a first gear provided at one end of the first output shaft, a second gear meshed with the first gear, a second output shaft provided with the second gear at one end and having an outer screw groove formed on an outer circumferential surface of a position spaced apart from the second gear in an axial direction and rotating in conjunction with the second gear, and a sliding member having an inner screw groove corresponding to the outer screw groove formed on an inner circumferential surface thereof, coupled to the second output shaft via a ball, and sliding in an axial direction to operate a link connected to vehicle wheels.

A steering apparatus includes a steering wheel, a support frame, a frame fixation part, and a steering transmission part. The support frame rotatably supports the steering wheel. The frame fixation part fixes the support frame to a vehicle body. The steering transmission part transmits a rotation of the steering wheel relative to the support frame to a steering mechanism of a wheel. The support frame and the frame fixation part are arranged at a position that does not overlap with a rotation center axis line of the steering wheel in a front view of the steering wheel.

A hand-wheel actuator for preventing over rotation of a hand-wheel shaft. The hand-wheel actuator comprises a housing that defines an opening aligned about an axis. The hand-wheel shaft extends along and is rotatable about the axis. A drive gear is rotationally coupled to the hand-wheel shaft, wherein the drive gear is at least partially disposed in the opening and includes a drive gear tooth. A stop gear is coupled to the housing and includes a plurality of stop gear teeth for engagement with the drive gear tooth and prevents rotation of the drive gear over a predetermined threshold.
