Steering Device

A steering device which steers a pair of wheels in accordance with a steering operation of a steering handle, comprising:

• a first motor operating in accordance with the steering operation of the steering handle;
• a first steering shaft steering one of the pair of wheels;
• a first conversion unit converting a comparatively low torque rotation of a first rotor as a rotation element of the first motor into an axial-direction movement of the first steering shaft with a comparatively high thrust;
• a second motor operating in accordance with the steering operation of the steering handle;
• a second steering shaft which is separated from the first steering shaft and steers the other of the pair of wheels;
• a second conversion unit converting a comparatively low torque rotation of a second rotor as a rotation element of the second motor into an axial-direction movement of the second steering shaft with a comparatively high thrust;
• and
• a coupling unit coupling the first rotor and the second rotor together and canceling the coupling of the first rotor and the second rotor.
