Abstract:
A torque detecting apparatus, comprising:drive-force-transmitting means which varies relative position of an output-side rotary body against a drive-source-side rotary body in correspondence with torque by way of transmitting drive force from said drive-source-side rotary body to said output-side rotary body via a predetermined elastic member; displacement detecting means which is held by one of said drive-source-side rotary body and said output-side rotary body and generates torque-modulated signal being modulated by torque signal in correspondence with variation of said relative position; signal transmitting means which transmits said torque-modulated signal to one of a stationary member fixed to said drive-source-side rotary body and a stationary member fixed to said drive-source-side rotary body and a stationary member fixed to said output-side rotary body under non-contact condition; signal processing means which outputs a result of torque detection in accordance with an output signal from said signal transmitting means; and detection result processing means for processing said torque-detected result; wherein:said drive-force transmitting means transmits drive force generated by pedaling force; said output-side rotary body drives one of a front wheel and a rear wheel via said drive force; and said detection result processing means generates drive force for assisting said pedaling force in accordance with said result of torque detection.
