1. A torque detector comprising:

  • (1) a first rotating member adapted for connection to a driving shaft of an internal combustion engine so as to be rotated therewith;

    (2) a second rotating member adapted for connection to a load, which is provided so as to be coaxially opposed to said first rotating member;

    (3) at least one elastic member for connecting said first rotating member to said second rotating member;

    said at least one elastic member deforming in response to torque applied to said first rotating member and producing an angular phase difference between said rotating members due to the deformation thereof;

    (4) an angular phase difference detecting means for detecting angular phase difference between said first rotating member and said second rotating member;

    (5) a no load condition detecting means for detecting a no load condition of said engine; and

    (6) a data processing means for calculating accurate torque from the angular phase difference between said first rotating member and said second rotating member under a load condition and under the no load condition,said no load condition detecting means supplying a no load condition signal to said data processing means when said engine is under the no load condition.
