ク検出装置。[Claims for Utility Model Registration] A torque transmitting means of a certain length capable of transmitting output side torque from a drive side electric motor, and a predetermined number of torque transmitting means fixed at constant intervals along the longitudinal direction of the torque transmitting means, each on the outer periphery. The method includes at least two rotating bodies having protrusions formed thereon, and first pickups that respond to the irregularities of the protrusions of each of the rotating bodies, and torque is detected from the phase difference between the outputs of the pickups corresponding to the respective rotating bodies. In the torque detection device, the at least two
one further second pick-up is added to both of the rotors, or one of the sides proximate to the electric motor, and the first and second pick-ups for each rotor are approximately 360 k/p degrees (360k/p) relative to each other; (k is an odd number), and the first and second pickups for each rotating body are electrically connected in series.
