PROBLEM TO BE SOLVED: To propose a fluctuant gearing device provided with a strain gauge type torque detection mechanism which is superior to durability. SOLUTION: An end face 23a of a boss 23 in a silk-hat-shaped flexible external gear 20 with an outer tooth of the fluctuant gearing device 1 and an end face 22a of a diaphragm 22 are taken as a continuous flat surface located on a coplanar and strain gauge 41 is affixed on a boundary portion of the end faces 23a, 22a. A resistance wire part 41b of the strain gauge 41 is affixed on diaphragm side of the end face 22a and connection terminal 41a is affixed on the boss side of the end face 23a. As all we have to do are to affix the strain gauge 41 on the flat surface, affixing work is easy and reliability to affix also enhances. A trouble such as disconnection does not occur because repeated deformation does not act on the connection terminal 41a affixed on the boss side. Consequently, durability of the torque detection mechanism enhances. COPYRIGHT: (C)2005,JPO&NCIPI
