PROBLEM TO BE SOLVED: To provide a torque detecting mechanism in which relative rotational amount (phase difference) between an input shaft and an output shaft can be suppressed small. SOLUTION: In the mechanism for detecting an input torque to a crankshaft 2 by detecting relative rotational amount between the crankshaft (input shaft) 2 and a resultant force shaft (output shaft) 4 arranged coaxially and rotatably each other through a resilient body, the resilient body comprising a leaf spring 25 is arranged while aligning the longitudinal direction thereof substantially with the input direction. Flexure displacement of the leaf spring 25 in the longitudinal direction is converted into axial displacement of a cam plate 31 supported slidingly by the crankshaft 2 and axial displacement of the cam plate 31 is converted through a cam mechanism (a cam 33 and a fulcrum pin 34) into rotational displacement of the cam plate 31 and detected by a displacement sensor 35.
