Abstract: A connector (130) is arranged between an inner support (110) and an outer support (120), and connects the inner support (110) and the outer support (120). A deformable body (140) has one end connected to the inner support (110) at a first position with respect to the direction of rotation about a Z-axis and the other end connected to the outer support (120) at a second position different from the first position, and is bent to be deformed in a radial direction by applying compressive force or tensile force between the first position and the second position. A detection body (150) includes a capacitative element including respective electrodes disposed to face the deformable body (140) and the outer support (120), and detects an elastic deformation generated in the deformable body (140) on the basis of the characteristic value of the capacitative element.

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.
