Claims

[Claims for Utility Model Registration] A first pin connected to the input shaft, a second pin spaced apart from the first pin in the radial direction and connected to the output shaft, and both ends of which are connected to the first and second pins. The torque of electric power steering consists of a spring that is arranged around a shaft to sandwich the input shaft, and that generates a relative torsional angular displacement between the input shaft and the output shaft according to the steering torque input to the input shaft. In the displacement conversion mechanism, the outer pin of the two pins has a larger diameter than the inner pin, and when the steering torque is zero, both ends of the spring simultaneously circumscribe both sides of the first and second pins. A torque-torsion angle displacement conversion mechanism featuring the following.
