PCT No. PCT/JP96/03588 Sec. 371 Date Sep. 8, 1997 Sec. 102(e) Date Sep. 8, 1997 PCT Filed Dec. 6, 1996 PCT Pub. No. WO97/21991 PCT Pub. Date Jun. 19, 1997An approximate straight line A1 of detected values showing magnetic impedance changes relative to a torque change obtained at an end portion (31a) of a body portion (31) of a cup-shaped flexible external gear (3) of a flexible meshing type gear inclines oppositely to an approximate straight line A2 of detected values showing magnetic impedance changes relative to a torque change obtained at a boundary portion (4) between a diaphragm (32) and a boss (33) of the flexible external gear. Based on these two approximate straight lines A1, A2, it is possible to obtain a torque detecting characteristic A3 that passes through a zero point and has a linearity. As a result of this, it is possible to realize a torque detecting device that can detect the rotational torque of the flexible meshing type gear with a configuration different from a conventional one and with accuracy. Based thereupon, it is possible to detect the rotational torque of the flexible meshing type gear with accuracy.
