Abstract
Coils,and magnetostriction elements,are disposed inside casings,fixed to a driving pulley housing,and an end of an outer tube,of a Bowden cable,is brought into abutment with the magnetostriction element,via a slider,When a steering torque is inputted into the steering wheel and an inner cable,is pulled in a direction indicated by an arrow B, an axial compression force acting on the outer tube,is transmitted to the magnetostriction element,via the slider,and a compression load p is applied thereto. This changes the magnetic permeability of the magnetostriction element,thereby changing the inductance of the coil,whereby the steering torque acting on the steering wheel can be detected based on the change in inductance. The torque detecting device for a cable-type steering device according to the present invention can securely detect a steering torque applied to a steering wheel with a simple construction and also can secure the rigid feel of the steering wheel to thereby prevent the deterioration of the steering feel.
