PROBLEM TO BE SOLVED: To maintain the relationship between a tire angle of a steered wheel and a steering wheel angle of a steering wheel constant by steering the steered wheel by a tire angle changing means on the basis of a detecting result of a steering wheel angle detecting means, and stopping rotation of the steering wheel when steering the steered wheel up to the tire end. SOLUTION: A large gear 15 as a rotary part is meshed with a small gear 14 installed on a rotary shaft 13 of a steering wheel 3 to detect a steering wheel angle of the steering wheel 3 from output of a steering wheel angle potentiometer 4 functioning as a steering wheel angle detecting means. A steered wheel 2 is steered by an electric motor 5 functioning as a tire angle changing means on the basis of a detecting result of the steering wheel angle potentiometer 4, and when steering the steered wheel 2 up to the tire end, rotation of the steering wheel 3 is stopped by an abutting part 21 and an abutting object part 22. |
