Abstract

PURPOSE:To reduce rotational friction force by crank connecting a work side rotation axis of an object to be measured which is subjected to rotational force with a rotation detecting axis provided with a coil spring that is balanced with the rotational force of an object to be measured. CONSTITUTION:An object W to be measured is pivoted by a jewel 15 and a plane stone 14 in which tenon 12a of a work side rotation axis 12 is thrusted into a receiving plate 17. A rotation axis 11 having a magnetic holder 3 carrying a magnet 4 fixed at the tip is pivoted by a jewel 5. At the same time, a balancing coil spring 6 is placed between a spring holding board 16 of the rotation axis 11 and a jewel receptacle 18. Further, the work side rotation axis 12 and the rotation axis 11 is connected with a cranklike connection 13. By this way, the rotational force of the object W to be measured is transmitted to the rotation axis 11 through the work side rotation axis 12 and connection 13, and the rotation axis 11 is rotated to a position where it is balanced with the coil spring 6. The rotational torque can be measured by measuring the angle of rotation with a magnetism detecting element 9 with reduced frictional force.
