PURPOSE:To execute a digital display of high accuracy with simple constitution, by expanding and transferring the rotary displacement of a torsion rod corresponding to rotary torque, to a potentiometer by use of a crank mechanism by a transfer rod, etc. which are interlocked and slid by being controlled by a cam, etc. CONSTITUTION:A torsion rod material 10 whose one end is fixed and whose other end is coupled with a rotary shaft 3 is elastically deformed, and is rotated and displaced together with the shaft in accordance with torque of the shaft 3. This displacement passes through the shaft 3, is transferred to the first transfer lever 19 whose axial direction position is controlled, through a correcting cam 22, and slides and moves the lever 19. As a result, the extent of rotary displacement of the shaft 3 is expanded through the second transfer lever which forms crank mechanism together with the lever 19, is transferred to a potentiometer 15, and the extent of rotary torque is digitally displayed with high accuracy by a mechanism which consists of simple constitution and generates a lot of errors. |
