Abstract
A force sensor according to the present invention includes: an annular deformable body arranged to surround an origin O when viewed in the Z-axis direction and configured to generate elastic deformation by application of one of a force and a moment; and a detection circuit that outputs an electric signal indicating one of the applied force and the moment on the basis of the elastic deformation generated in the deformable body. The deformable body includes: two fixed portions fixed with respect to the XYZ three-dimensional coordinate system; two force receiving portions positioned alternately with the fixed portions in a circumferential direction of the deformable body and configured to receive application of one of the force and the moment; and four deformable portions positioned between the fixed portion and the force receiving portion adjacent to each other in the circumferential direction of the deformable body, and each of the deformable portions includes a curved portion protruding in the Z-axis direction, and the detection circuit outputs the electric signal on the basis of elastic deformation generated in the curved portion.
