Abstract
An inner support member, a detection deformable body, and a ring-shaped outer support member are disposed sequentially from the inside to the outside around a Z axis as a central axis. Inner surfaces in the vicinity of inner support points of the detection deformable body connect to outer surfaces of the inner support member via inner connecting members, and outer surfaces in the vicinity of outer support points of the detection deformable body connect to inner surfaces of the outer support member via outer connecting members. When a torque acts in the clockwise direction on the outer support member (130) while the inner support member is fixed, detection parts are displaced outwardly, and detection parts are displaced inwardly. These displacements are detected electrically as changes in capacitance values of four capacitor elements including opposing electrodes.
