  • Steering torque detecting device
    Patent number: 5195383
    Abstract: A steering torque is transmitted from a steering wheel side rotary member to a steering shaft side rotary member through a plurality of elastic bodies, when a steering wheel is turned. The elastic bodies are provided around a rotational center of a steering shaft which bending parts. A relative rotation produced between the steering wheel side rotary member and the steering shaft side rotary member is detected by detecting coils, because the detecting coils detect the change of the reluctance of the magnetic circuit of the rotary members and the detecting coil.
