Abstract
The present invention provides a novel torque detecting apparatus capable of detecting torque with a simple structure and high precision by way of transmitting drive force via a pair of rotary bodies that cause own relative position to be varied by effect of torque to enable detection of variation of resonant frequency corresponding to variation of the relative position under non-contact condition or by way of transmitting drive force via a pair of rotary bodies that cause own relative position to be varied by effect of torque to enable transmission of modulated signal corresponding to variation of the relative position under non-contact condition.
