<p>PROBLEM TO BE SOLVED: To reduce a manufacturing cost. SOLUTION: In this torque sensor for detecting torque by utilizing the change of the overlapping degree of plural grooves 3a extended in an axial direction and the windows 10a and 10b of a cylindrical member 10 surrounding them, a groove formation member 3A for which the grooves 3a are formed on an outer peripheral surface is turned to the member different from an output shaft 3, the grooves 3a are integrally formed on the groove formation member 3A by cold forging and the groove formation member 3A where the grooves 3a are formed is forcibly fitted and fixed to the end part of the output shaft 3 while appropriately matching phases.</p> |
