PROBLEM TO BE SOLVED: To acuurately and quickly conduct detection even when an excessive driving torque is applied to a motor. SOLUTION: This detector detects a driving torque of the motor 2 provided on a frame 9 supported by an output shaft 5, of which the rotational drive is transmitted to the output shaft 5. The gear frame 9 is supported onto the output shaft 5 in a suspended condition via a reduction gear 4 in its longitudinal- directional one end side, and is supported from a lower side by a load cell (reaction detecting part) 11 attached with respect to a floor part 10 therebetween in the longitudinal-directional other end side. The load cell 11 is such one as electric resistance of a strain gage provided in its inside is varied in response to a tension load to vary an electric current, when the load is applied, and the current variation is measured to find the tension load. The load is detected to detect the driving torque of the motor 2. |
