Claims

[Scope of utility model registration request]

(1) A cylindrical control shaft coaxially attached to the steering handle, a cylindrical pinion coaxially inserted into the lower part of the control shaft, and a cylindrical pinion inserted into the control shaft and pinion, with the upper end attached to the control shaft. The lower end includes a torsion bar spring connected to each pinion, and when the steering handle is rotated, the pinion rotates via the torsion bar spring, and the rack that engages with the pinion moves in its axial direction to perform steering. A rack and pinion steering device includes a sensor mechanism that detects the rotational direction and steering torque of a steering wheel and generates a signal, an electric motor that drives the pinion, and a signal input from the sensor mechanism to determine the rotational direction and output of the electric motor. An electric power steering device consisting of a control circuit that sets the

(2) The sensor mechanism includes a cam 1 ring fitted on the outer peripheral surface of the control shaft and a cam ring that is movable in the axial direction of the control shaft according to the direction and amount of angular displacement of the control shaft with respect to the pinion, and the amount of movement of the cam ring. The electric power steering device according to claim 1, which is a registered utility model and comprises a torque sensor arm that amplifies and a potentiometer that generates a signal corresponding to the direction and amount of operation of the torque sensor arm.
