Abstract: A steer-by-wire steering device includes a first member, a second member, and stoppers. The first member is rotatable together with the input shaft, and includes a first protrusion protruding from the input shaft in the radial direction. The second member includes a second protrusion protruding on the trajectory of the first protrusion, and is rotatable together with the first member with the first protrusion being abutting the second protrusion. The stoppers are provided at respective positions capable of abutting on the trajectory of the second protrusion only when the second member is rotated by the first member.

Abstract: A steer-by-wire steering device includes a first member, a second member, and a stopper. The first member includes a first base surrounding an input shaft and rotatable, a first protrusion protruding from the first base in a radial direction or in an axial direction, and a first weight provided on the first base so as to make a weighted center consistent with a center of the input shaft. The second member is rotatable together with the first member with the first protrusion being abutting the second protrusion. The stopper is provided on a trajectory of the second protrusion, and is capable of restricting the turn of a steering wheel via the input shaft when abutting with the second protrusion.

Abstract: A steering device includes a motor, a first shaft, a transmitter, a second shaft, and an engagement portion. The first shaft of a hollow cylindrical shape is coupled in a torque transmittable manner to a steering member with which a driver performs steering operation. The transmitter is disposed on an outer circumference of the first shaft and configured to transmit torque of the motor to the first shaft. The second shaft is coupled in a torque transmittable manner to a wheel-turning unit configured to turn wheels. The second shaft is inserted in the first shaft. The engagement portion is interposed between an inner surface of the first shaft and an outer surface of the second shaft and configured to make the first shaft and the second shaft engage with each other.
