Abstract
A torque detecting device, which is typically used for detecting a steering torque in a motor vehicle, includes a mechanism for converting the torque applied to an input shaft to an axial force between the input shaft and an output shaft. A slider is fitted about the output shaft movably axially along the output shaft and rotatably about its own axis with the output shaft. The axial movement of the slider is electrically detected. An elastic body is provided for returning the input shaft to its neutral position. The converting mechanism has a pin extending through the input shaft at right angles thereto and having two ends projecting therefrom. A pair of slits each having a pair of ends are formed in the output shaft. Each of the ends of the pin is located in one of the slits engageably with either end thereof. A bearing is secured to one end of the pin. A spiral groove is formed in the slider and one end of the pin extends into the groove to dispose the bearing therein.
