Patent

CA 2732056

To provide a torque detection device for a power steering which is not complicated in structure and which is less liable to be influenced by external factors or by a bending force exerted on a shaft. The torque detection device for the power steering is so configured that a torque generation between an input shaft, which is turned interlockedly with a steering handle for operating the traveling direction of a vehicle, and an output shaft turned interlockedly with the input shaft so as to steer a wheel or wheels is detected, and that an assisting force exerted on the output shaft by an assisting unit is determined based on the detection result. The torque detection device is provided between the input shaft and the output shaft and includes a cam mechanism by which a torque generated between the input shaft and the output shaft is converted into a thrust force, and a pressure sensor for detecting the thrust force into which the torque is converted by the cam mechanism.
