ABSTRACT:
An electric power steering apparatus which includes: an input shaft connected to a steering wheel; a torque sensor mechanism having a torque sensor which detects a steering torque on the basis of a relative displacement of the input shaft and the output shaft connected to the input shaft via a torsion bar; and a reduction mechanism which reduces a rotation of a steering assisting electric motor driven on the basis of a result detected by the torque sensor and transmits it to the output shaft. The torque sensor mechanism is arranged to the steering mechanism side from the reduction mechanism, so that an energy absorption stroke can be further made long without varying a mount point of the electric motor and a column mount length.
