<p>PROBLEM TO BE SOLVED: To provide a power steering device to precisely detect steering torque and secure the reliability. SOLUTION: A protrusion 2b formed on a input shaft 2 is engaged with a lower peripheral groove 5e formed on a torsion bar 5 to eliminate the movement of the input shaft 2 and the torsion bar 5 in the axial direction even when an impact force is generated during travel or the like of a vehicle thereby the steering torque can be precisely detected.</p> |
