Abstract: A torque sensor according to the present invention includes a strain body, first structure Y-axis connecting portions, second structure X-axis connecting portions and a detection element. The first structure Y-axis connecting portions are disposed on a positive side and a negative side of a Y-axis relative to the strain body, and the second structure X-axis connecting portions are disposed on a positive side and a negative side of an X-axis relative to the second structure. The strain body includes four deformable bodies each including a displacement portion that is displaced in a Z-axis direction by elastic deformation. The deformable bodies are respectively disposed in a first quadrant, a second quadrant, a third quadrant, and a fourth quadrant. The detection element includes a capacitive element that detects a change in capacitance value by a displacement of the displacement portion of each of the deformable bodies in the Z-axis direction.

Abstract: A strain body of a force sensor according to the present invention includes a tilting structure disposed between a force receiving body and a support body, a force-receiving-body-side deformable body connecting the force receiving body and the tilting structure, and a support-body-side deformable body connecting the tilting structure and the support body. The tilting structure includes a first tilting body that extends in a second direction orthogonal to a first direction and that is elastically deformable by the action of force in the first direction.
